A photo straight off a phone camera can easily be 4-8MB, which is overkill for a website, a WhatsApp share, or a college application form with a strict size limit. Compression shrinks that file without throwing away the picture itself, by re-encoding the pixel data more efficiently.

Lossy vs lossless compression

JPEG compression is "lossy" — it groups similar-looking pixels together and discards detail the human eye barely notices, especially in smooth areas like sky or skin tones. PNG compression is "lossless" — it keeps every pixel exact, which is why PNGs of photographs are usually much larger than an equivalent JPEG. That's why our compressor lets you pick a quality level: lower quality means a smaller file but slightly softer detail in busy areas of the image.

What actually happens in your browser

When you drop a file into the compressor, it's decoded onto an HTML canvas, re-encoded at your chosen quality, and handed back to you as a new file — all inside your own browser tab. Nothing is uploaded to a server in the process, which is both faster and more private than most online compressors that quietly send your images off to be processed remotely.

Getting the best result

• Start around 70-80% quality — most people can't tell the difference from the original at this range.
• For photos with lots of fine texture (leaves, fabric, crowds), keep quality slightly higher than for simple graphics.
• If a form asks for a file under a specific size like 200KB, compress in a couple of passes and check the output size after each one.

Compression works best on photographs; if you're compressing a screenshot with sharp text, consider our PNG-friendly settings or resizing the image down first, since smaller dimensions often shrink the file more than quality reduction alone.

Resizing changes the pixel dimensions of an image — how many pixels wide and tall it is — which is different from compression, which changes how efficiently those pixels are stored. You'll usually resize for a specific requirement: a profile picture that must be exactly 400x400px, a banner that needs to fit a fixed width, or a photo that's simply larger than any screen will ever display it.

Keeping the aspect ratio locked

If you type a new width without preserving the original ratio, the image will look stretched or squashed. Our resizer locks width and height together by default, so entering one dimension automatically calculates the other — you can unlock this if you deliberately need a non-standard shape, but for most everyday uses keeping it locked avoids distorted photos.

Upscaling vs downscaling

Making an image smaller (downscaling) is generally safe — you lose some detail but the result usually still looks sharp. Making an image larger (upscaling) is trickier: the tool has to invent new pixel information that wasn't there before, which is why an image stretched far beyond its original size often looks soft or blurry. If you need a much larger version of a small photo, treat the result as an approximation rather than a true high-resolution copy.

Common resize targets

• Website hero images: usually 1600-1920px wide is enough, even for large monitors.
• Social media profile photos: most platforms use somewhere between 320px and 800px square.
• Form or document uploads: check the exact pixel requirement stated on the form rather than guessing.

Everything runs locally in your browser using canvas resampling, so your original file never leaves your device — you just download the resized version once you're happy with the preview.

Cropping removes the parts of an image you don't need, which is often more useful than resizing when the goal is to change what's shown rather than how large the file is — think cutting a person out of a group photo, tightening a screenshot around just the relevant part of a screen, or preparing an image for a fixed aspect-ratio slot like a square avatar.

Free-form crop vs fixed ratio

A free-form crop lets you drag the selection box to any shape, which is useful when you know exactly what you want to keep. A fixed-ratio crop — square (1:1), portrait (4:5), widescreen (16:9) — constrains the box to a specific proportion, which matters when the destination has a strict shape requirement, like an Instagram post or a passport-style photo slot.

Composition tips while cropping

• Leave a little breathing room around a face or subject rather than cropping right up to the edge.
• For text-heavy screenshots, crop a few pixels wider than the text block so nothing gets clipped.
• Preview the crop at actual size before downloading — a selection that looks fine zoomed out can crop awkwardly at full resolution.

The crop preview and the final export both happen on-device using canvas, so you can try several crop positions and ratios before committing, and only the final cropped image is generated as a downloadable file — nothing is sent anywhere in between.

Not every format suits every situation. JPG is the default for photographs because it compresses well without an alpha (transparency) channel. PNG supports transparency and is lossless, which makes it the right choice for logos, icons, and screenshots with sharp edges and text. WebP is a newer format that often produces smaller files than both, at similar quality, and is now supported by virtually every modern browser.

When to convert to PNG

Convert to PNG when you need a transparent background — for example a logo that needs to sit on top of different colored sections of a website — or when the image has flat colors and hard edges, like a diagram or a chart, where PNG's lossless encoding avoids the blurring artifacts JPEG can introduce around text.

When to convert to JPG or WebP

For ordinary photographs meant for web pages, emails, or messaging apps, JPG remains the safest, most universally compatible choice. If your target platform accepts WebP — most modern websites and even many chat apps do — converting there usually gives a noticeably smaller file at the same visual quality, which matters on slower connections.

A quick decision guide

• Photo for a website or social post → JPG or WebP.
• Logo, icon, or image needing transparency → PNG.
• Smallest possible file at good quality, and the platform supports it → WebP.

The converter reads the original file, re-encodes the pixel data into the target format, and lets you download the result — all inside your browser, without a round trip to any server.

Removing a background turns the area around your subject transparent, so the image can be placed on any color, banner, or document — a common need for product photos, profile pictures, ID-style photos, and simple graphic design work where you want just the subject, not whatever was behind it.

What makes a background easy or hard to remove

A subject photographed against a plain, evenly lit background — a wall, a solid backdrop, or an overcast sky — is the easiest case, because there's a clear contrast between subject and background. Backgrounds with similar colors to the subject, motion blur, or wispy details like loose hair strands are harder, and the edge of the cut-out may need a manual touch-up afterward in an image editor.

Exporting the result correctly

Once the background is removed, always export as PNG rather than JPG — JPG doesn't support transparency, so saving in that format will fill the transparent area with a solid color (usually white) instead of keeping it see-through. If you need the cut-out on a specific colored background, add that background after exporting, either in the same session or in any basic photo editor.

Practical uses

• Product photos for an online store, placed on a clean white or brand-colored background.
• Profile pictures where you want just the person, without their original surroundings.
• Quick graphic elements for presentations or thumbnails.

Processing happens directly in your browser, so the photo you upload is never sent to an external server for background removal.

A lot of everyday paperwork — assignment submissions, ID proof, scanned forms — is expected as one PDF, even though what you actually have is a handful of photos taken on a phone. Converting JPGs to PDF solves exactly this: each image becomes a page in one document, in whatever order you choose.

Getting page order and orientation right

Before converting, arrange your images in the order you want them to appear as pages — most tools let you drag to reorder the thumbnails. Check that none of the photos are sideways or upside down; a phone photo taken at an angle will carry that same rotation into the PDF unless it's corrected first.

Page size and margins

Each image is placed onto a page, usually sized to A4 by default, either fitted to the page width or scaled to fill the page depending on the tool's settings. If your images have very different aspect ratios — one portrait, one landscape — expect some white space around the shorter dimension so nothing gets stretched out of proportion.

When this is the right tool

• Submitting scanned assignment pages or handwritten notes as one file.
• Combining multiple ID or document photos into a single upload.
• Turning a set of receipts or bills into one shareable PDF.

The conversion happens entirely client-side — your photos are read, laid out as PDF pages, and packaged for download, without being uploaded anywhere in the process.

Sometimes you need the opposite of a PDF — a single page or diagram as a plain image you can paste into a chat, a slide, or a document. Converting a PDF to JPG renders each page of the file as its own image, which you can then use anywhere a PDF wouldn't be accepted.

One image per page

A multi-page PDF converts into a matching set of images, one per page, which you can download individually or, depending on the tool, all at once. If you only need a single page from a longer document, look for an option to select just that page rather than converting the whole file.

Image quality and resolution

Because a PDF page is essentially a vector or high-resolution description of content rather than a fixed-size photo, the resulting JPG's sharpness depends on the resolution the conversion renders at. For text-heavy pages you want to zoom into later, choose a higher output resolution so the text stays crisp instead of turning blurry when enlarged.

Typical uses

• Pulling a chart or diagram out of a report to drop into a presentation.
• Sharing a single page of a form over WhatsApp instead of the whole PDF.
• Getting a quick thumbnail preview of a document's contents.

The rendering happens in your browser using the PDF's own page data, so the file you convert is never uploaded to an external service.

Merging PDFs is one of those small tasks that comes up constantly — a resume plus a cover letter, several scanned chapters of notes, or a set of certificates that need to be submitted as a single file. Instead of installing desktop software, merging can be done entirely in the browser in a few seconds.

Getting the page order right

The order you add files in determines the order they appear in the final document, so it's worth double-checking the sequence before merging — most merge tools let you drag files up or down in the list to fix the order without having to re-upload anything.

What happens to bookmarks and formatting

A straightforward merge preserves each source PDF's pages exactly as they were — fonts, images, and layout stay untouched — it simply stitches the page sequences from each file together into one. Bookmarks or internal links specific to a single source file typically don't carry over automatically, since they were built around that file's own page numbers.

Where this is handy

• Combining a resume, cover letter and certificates into a single application PDF.
• Merging scanned pages of the same document that were scanned in separate batches.
• Putting together multiple invoices or receipts into one file for records.

Everything is processed locally — the files you select are combined directly in your browser and the merged PDF is generated for you to download, without ever being sent to a server.

Government portals, college admission forms and email attachments often cap upload size in KB or MB, and a PDF full of scanned pages or high-resolution images can blow past that limit fast. Compressing trades a little visual detail for a much smaller file, which is usually a fair trade for forms and documents that just need to stay readable.

How PDF compression works here

Each page is redrawn onto a canvas at a chosen resolution and re-saved as a JPEG inside a new PDF. Lower resolution and JPEG quality mean a smaller file; higher settings keep more detail but shrink the file less. That's why there are three levels to choose from instead of one fixed setting.

Choosing a compression level

• Low compression — best for PDFs with photos or fine print where quality matters most.
• Recommended — a balanced setting that works well for most scanned documents and forms.
• High compression — best when you need the smallest possible file, such as for a strict upload size limit.

Everything runs locally in your browser using a PDF-rendering library loaded from a public CDN — your file is never uploaded to a server.

Splitting a PDF comes up whenever a single file actually contains several separate documents — a scanned bundle of invoices, a report where only one chapter needs sharing, or a set of certificates bundled together by mistake. Doing this without desktop software just means pulling the exact pages you need back out of the original file.

Two ways to split

Splitting every page into its own file is useful when a scanner or bulk export has combined pages that were never meant to be together. Extracting a specific range is more common when only a portion of a longer document — a chapter, an appendix, a signed page — needs to be shared on its own.

What stays intact

Because pages are copied directly rather than rasterized, text stays selectable and searchable, and any images on the page keep their original resolution — the output pages are identical to the source, just regrouped into new files.

Where this is handy

• Pulling a single signed page out of a longer contract to send on its own.
• Separating a scanned batch of receipts or forms back into individual files.
• Sharing one chapter of a report without sending the entire document.

Everything runs locally — the PDF you choose is read and split directly in your browser, and the result downloads straight to your device without ever touching a server.

A clear invoice gets paid faster. At a minimum it needs your business details, the client's details, a unique invoice number, the date, an itemised list of what's being billed, and a total that's easy to find at a glance.

Invoice numbers

A simple sequential format like INV-0001, INV-0002 keeps records easy to search and matches what most accounting software expects, which matters if you ever need to reconcile books later.

GST for Indian freelancers and small businesses

If you're registered for GST, add your GSTIN and set the GST percentage — the tool automatically splits it into CGST and SGST for an intra-state bill when the currency is set to ₹.

Where this is handy

• Freelancers and students billing clients for project work.
• Small businesses that need a quick invoice without spreadsheet software.
• One-off sales or service bills that need a proper paper trail.

Everything is calculated and rendered locally in your browser — nothing you type is sent to a server.

Passport and visa photo rejections are usually caused by a handful of repeat mistakes — wrong size, a background that isn't plain white, or a headshot that isn't cropped tightly enough — rather than the photo quality itself. Knowing the actual rules in advance saves a second trip to a photo studio.

Size and background rules

Indian passport photos are typically required at 2x2 inches (51x51mm) with a plain white or very light background, the face centered and looking straight at the camera, with a neutral expression and no shadows across the face. Different countries' visa photos sometimes use slightly different dimensions, so it's worth checking the exact requirement for wherever you're applying.

Common rejection reasons

• Background isn't plain — shadows, patterns, or furniture visible behind the subject.
• Face is too small or too large within the frame, instead of filling the specified proportion.
• Photo is tinted, has a filter applied, or shows glare on glasses.
• Head is tilted, or the expression isn't neutral as required.

How the tool helps

Our passport photo maker crops your photo to the correct official dimensions, helps you align the face within the required guides, and can standardize the background — so the finished photo matches the technical spec before you print or upload it, cutting down the chance of a rejection at the counter.

As with our other image tools, the cropping and resizing happens directly in your browser, so your photo isn't uploaded to generate the final result.

A watermark is a visible mark — text or a logo — layered on top of an image, mainly used to discourage unauthorised use or to keep a brand visible when a photo is shared or reused elsewhere. Photographers, small businesses, and content creators use them most often on portfolio images and product photos.

Text watermark vs logo watermark

A text watermark is quick to add and works well for a simple copyright line or a website name across the bottom of an image. A logo watermark gives a more polished, branded look but needs a transparent PNG of the logo to place cleanly over the photo without a distracting white box behind it.

Placement and opacity

A watermark placed dead-center is the hardest to crop out, but it can be distracting for portfolio work where you want the photo itself to stand out. A corner placement at moderate opacity — visible enough to identify the source, but not overpowering the image — is the more common choice for most everyday sharing.

Quick tips

• Keep opacity around 40-60% so the watermark is visible without dominating the photo.
• Use a repeating diagonal watermark across the whole image if the goal is stronger protection against unauthorized reuse.
• Match the watermark's font or logo style to your brand for a more consistent, professional look.

The watermark is drawn onto the image using canvas directly in your browser, so you can preview different positions and opacities before downloading the final version.

A digital signature image is simply a picture of your signature — hand-drawn, typed, or scanned — saved as a file you can paste into documents instead of printing, signing and re-scanning paperwork every time.

Drawn vs typed vs uploaded

A drawn signature, made with a mouse, trackpad or touchscreen, looks the most personal but can be harder to get right without a stylus. A typed signature using a handwriting-style font is quick and consistent, and works well for informal use. An uploaded signature, from a photo of your signature on paper, keeps your actual handwriting and is the closest to a traditional pen-and-paper signature.

Why transparent background matters

A transparent PNG lets your signature sit cleanly on top of a form, contract or letterhead without a white box around it. If the document you're signing has a white background anyway, a white-background version works just as well and can be smaller in file size.

Quick tips

• For an uploaded signature, sign in dark ink on plain white paper and photograph it in good, even light for the cleanest background removal.
• Keep a drawn or typed signature simple — it's easier to reproduce consistently across documents.
• Save a few versions (drawn, typed, and a scanned one) so you have the right style for different situations.

Everything here runs on the canvas element directly in your browser, so you can try each method and compare before downloading.

Most recruiters and hiring managers spend only a few seconds scanning a resume before deciding whether to read further, which means structure and clarity matter as much as the content itself. A clean, well-organized resume built from a proven template gets noticed faster than a cluttered one, even with similar experience listed.

What belongs at the top

Your name, contact details, and a short summary or objective line should be immediately visible without scrolling. If you're a student or early in your career, put your education and any relevant projects or internships near the top; if you have several years of experience, lead with your most recent and relevant roles instead.

Formatting choices that matter

• Stick to one or two fonts and consistent heading sizes throughout the document.
• Use bullet points for responsibilities and achievements rather than long paragraphs.
• Keep it to one page unless you have extensive, directly relevant experience that genuinely needs more space.
• Quantify achievements where possible — numbers stand out far more than general descriptions.

Before you export

Proofread carefully for typos and inconsistent tense (mixing "managed" with "manage" across bullet points is a common slip), and double check that your contact information is current before generating the final PDF or document.

Our resume maker fills a proven layout with your details as you type, so you can preview the finished look and download it directly, without needing any design software.

A QR code is just a compact, machine-readable way of storing text — a URL, a phone number, a WiFi password, contact details — as a pattern of black and white squares that any phone camera can decode instantly. Generating one takes seconds, but a few small choices affect how reliably it scans in the real world.

What you can encode

Beyond a plain website link, QR codes can hold plain text, an email address, a phone number that opens the dialer, or WiFi credentials that connect a phone automatically when scanned — useful for a café's guest network or an event's registration link printed on a poster or business card.

Keeping it scannable

• Leave a quiet, empty margin around the code — cropping too close to the edge can break scanning.
• Print or display it large enough that a phone camera from a normal distance can resolve the individual squares.
• Test the code with more than one phone before printing it in bulk on posters or packaging.
• Avoid stretching the code non-uniformly — keep it perfectly square.

A note on error correction

QR codes include built-in redundancy, which is why a code can still scan even if part of it is smudged, covered by a small logo, or slightly damaged — up to a point. It's still worth testing after printing rather than assuming it'll work purely because it looked fine on screen.

The generator builds the code directly in your browser from whatever text you enter, so you can download it as an image immediately without any account or server round-trip.

Optical Character Recognition (OCR) analyses the shapes in an image and matches them against known letterforms to reconstruct the actual text, so a photo of a printed page, a screenshot, or a scanned document becomes editable, searchable, copy-pasteable text instead of just a picture.

What makes OCR accurate

Accuracy depends heavily on image quality: clear, well-lit, non-blurry photos with the text roughly horizontal give the best results. Handwriting is far harder for OCR than printed text, and low-resolution or heavily compressed images tend to introduce recognition errors, especially with small font sizes.

Improving your results

• Photograph the page straight-on rather than at an angle, to avoid distorted, curved text lines.
• Make sure the lighting is even, without strong shadows falling across part of the text.
• Crop out irrelevant background before running OCR, so the tool focuses only on the text region.
• Always proofread the extracted text — even good OCR occasionally confuses similar-looking characters like 0/O or 1/l.

Common uses

People use image-to-text to pull quotes out of a photographed book page, digitize a printed form, extract text from a screenshot of an error message, or turn a whiteboard photo from a meeting into notes they can actually search and edit later.

The recognition runs directly in your browser using an on-device OCR engine, so the image you upload for text extraction isn't sent to an external server.

A scientific calculator adds trigonometric functions, logarithms, exponents, and often memory storage on top of the four basic operations, which covers most of what's needed for school and college-level maths, physics, and engineering coursework without switching to specialised software.

Order of operations still applies

Just like on paper, a scientific calculator follows standard mathematical order of operations (brackets, exponents, multiplication and division, then addition and subtraction). When a calculation gives an unexpected result, the most common cause is missing or misplaced brackets rather than a calculator error — grouping terms explicitly avoids ambiguity.

Degrees vs radians

Trigonometric functions behave completely differently depending on whether the calculator is set to degrees or radians — sin(30) in degree mode gives 0.5, but sin(30) in radian mode gives a very different number. If a trig answer looks obviously wrong, checking the angle mode is usually the first thing to fix.

A few practical tips

• Use memory functions to store an intermediate result rather than re-typing a long number.
• Double check the angle mode before starting any trigonometry problem.
• For very large or very small numbers, scientific notation keeps the display readable and avoids rounding confusion.

Our calculator runs entirely in the browser, keeping a visible history of your recent calculations so you can retrace a multi-step problem without losing earlier results.

Body Mass Index (BMI) is a simple ratio of weight to height, calculated as weight in kilograms divided by height in metres squared. It's widely used as a quick population-level screening number because it only needs two easy-to-measure inputs, but it's worth understanding exactly what it can and can't tell you about an individual.

The standard BMI categories

Most health guidelines place a BMI under 18.5 as underweight, 18.5-24.9 as a normal range, 25-29.9 as overweight, and 30 and above as obese, though some Asian population guidelines use slightly lower cutoffs given differences in average body composition at a given BMI.

Why BMI has limits

BMI doesn't distinguish between muscle and fat, so a very muscular person can show a high BMI while carrying very little body fat, and it doesn't account for where fat is distributed on the body, which some research considers more relevant to health risk than the overall number alone.

Using the number sensibly

• Treat BMI as one general indicator, not a complete health assessment.
• Track the trend over time rather than reacting to a single reading.
• If BMI falls outside the typical range, a doctor can put it in context alongside other measurements.

This tool is meant for a quick, informational estimate and isn't a substitute for medical advice — if you have concerns about your weight or health, it's worth discussing with a doctor who can look at the full picture.

An EMI (Equated Monthly Instalment) is a fixed amount you pay every month toward a loan, combining both principal repayment and interest, calculated so that the entire loan is paid off in equal instalments over the agreed tenure. The formula factors in the loan amount, the annual interest rate, and the number of months in the tenure.

Why early instalments are mostly interest

In the early months of a loan, a larger share of each EMI goes toward interest and only a small portion toward reducing the actual principal — this shifts gradually over the loan's life, with later instalments paying down more principal and less interest. This is why closing a loan early can save meaningfully more interest than it might first appear to.

What changes your EMI amount

• A longer tenure lowers the monthly EMI but increases the total interest paid over the life of the loan.
• A higher interest rate increases the EMI for the same loan amount and tenure.
• A larger down payment reduces the loan principal, which reduces both the EMI and the total interest.

Using the calculator to compare offers

When comparing loan offers from different lenders, run the same loan amount and tenure through the calculator for each interest rate on offer — a difference of even half a percentage point in rate can add up to a noticeable amount over a multi-year tenure, so it's worth comparing the total interest, not just the EMI figure.

Enter the loan amount, interest rate, and tenure, and the calculator instantly shows your monthly EMI along with the total interest and total amount payable over the loan's life.

GST (Goods and Services Tax) is applied in India at rates that commonly include 5%, 12%, 18%, and 28% depending on the category of goods or services. The confusion most people run into isn't the tax rate itself, but whether they need to add GST on top of a price or extract it from a price that already includes tax.

Adding GST to a base amount

If you have a base price before tax, adding GST is straightforward: multiply the base amount by the GST rate and add that to the original price. For example, an 18% GST on a base amount of ₹1,000 adds ₹180, making the final price ₹1,180.

Removing GST from a total amount

This is where people most often make an error — you can't simply subtract the tax percentage from the total, because the percentage was calculated on the base amount, not the total. To find the original base amount from a GST-inclusive total, divide the total by (1 + GST rate as a decimal). For a ₹1,180 total at 18% GST, that's 1180 ÷ 1.18, giving back the original ₹1,000 base.

CGST vs SGST vs IGST

• CGST and SGST apply in equal halves for transactions within the same state (e.g. 9% + 9% for an 18% rate).
• IGST applies as a single combined rate for transactions between two different states.

Our calculator handles both directions — adding GST to a base price, or extracting it from a GST-inclusive total — and shows the CGST/SGST or IGST split automatically.

PDF and Word (.docx) serve different purposes — Word is meant to be edited, PDF is meant to look identical everywhere it's opened. Converting between them is common: a report drafted in Word needs to be shared as a fixed PDF, or a PDF form needs its text edited back in Word.

Word to PDF: what stays intact

Converting from Word to PDF generally preserves fonts, layout, images and page breaks exactly as they appeared in the original document, which is exactly why PDF is the standard format for sharing a finished document — the recipient sees the same layout you designed, regardless of what software or device they're using to open it.

PDF to Word: what to expect

Converting the other way is more variable, because a PDF doesn't inherently store the same kind of structured, editable text and layout information that a Word document does. Simple, mostly-text PDFs convert cleanly into an editable document; PDFs with complex multi-column layouts, tables, or scanned images may need some manual formatting clean-up afterward.

A few tips

• For a document you plan to keep editing, keep the original Word file and only convert to PDF for the final shared version.
• If converting a scanned PDF, check whether the text was extracted correctly — a purely scanned image page has no underlying text to convert until OCR is applied first.
• Always review the converted file before sending it onward, especially tables and multi-column sections.

Markdown is the plain-text formatting language behind READMEs, wikis, note-taking apps and most AI chat tools. Converting a document into Markdown strips away proprietary formatting while keeping headings, lists and tables readable as plain text — making the content easy to paste into a chat, a static site, or a notes app.

What each format gives you

• PDF — the readable text is extracted page by page, with paragraph breaks preserved as closely as the PDF's structure allows.
• Word (.docx) — headings, bold/italic text, lists and links carry over from the document's own formatting.
• Excel (.xlsx / .xls) — each sheet becomes a Markdown table, so rows and columns stay aligned.
• PowerPoint (.pptx) — each slide's text becomes its own heading and bullet list.
• YouTube — the title, channel name and description are pulled in as a short Markdown snippet with a link back to the video.

A few tips

• Scanned PDFs (photos of text with no underlying text layer) won't extract cleanly — try the Image to Text tool first.
• Complex layouts, multi-column pages, and heavily nested tables may need a quick manual clean-up afterward.
• Always double-check the output before pasting it somewhere important.

CTC (Cost to Company) is the total amount a company spends on an employee annually, and it's usually a bigger number than what actually shows up as take-home pay every month. The gap between the two is made up of several components that don't arrive as cash in your bank account.

What's included in CTC but not in-hand pay

• Employer's contribution to Provident Fund (PF), which goes into a retirement account rather than your salary account.
• Gratuity, which is only paid out under specific conditions, typically after a minimum number of years of service.
• Insurance premiums the company pays on your behalf, such as health or life insurance cover.
• Other benefits like meal vouchers or reimbursement allowances, which may only be usable for specific categories of spend.

What actually reduces in-hand pay further

On top of the CTC-to-in-hand gap, income tax and your own PF contribution are deducted from what would otherwise be your monthly cash salary, which is why the number in an offer letter can feel noticeably larger than what actually reaches your account each month.

Why this matters when comparing offers

Two offers with the same CTC can result in quite different monthly take-home pay, depending on how much of that CTC is structured as fixed cash salary versus benefits, bonuses, and employer contributions. When comparing job offers, it's worth breaking down the full CTC structure rather than comparing the headline number alone.

Enter your CTC and its components, and the calculator breaks down your likely monthly in-hand salary after typical deductions.

SGPA reflects how you did in a single semester, calculated from the credits and grade points of each subject you took that term. CGPA rolls every completed semester's SGPA together into one cumulative number, weighted by how many total credits each semester carried.

Why credits matter more than a simple average

A semester with heavier subjects (more total credits) pulls your CGPA toward its SGPA more strongly than a lighter semester does. This is why simply averaging your semester SGPAs together, without accounting for credit differences, can give a noticeably different — and often incorrect — CGPA compared to the properly credit-weighted calculation.

The formula in plain terms

Multiply each semester's SGPA by that semester's total credits, add all of those products together, then divide by the sum of all the credits across every semester. The result is your CGPA — automatically weighted so heavier semesters count proportionally more.

Where students get tripped up

• Assuming all semesters carry the same credits, when in fact many colleges vary credit load year to year.
• Using the wrong grade-point scale for a subject that was audited or graded on a different system.
• Forgetting to include a semester where a backlog subject was later cleared and its SGPA recalculated.

Enter each semester's SGPA and credits, and the calculator applies the correct credit-weighted formula automatically, so you don't have to do the multiplication and division by hand every semester.

Most Indian colleges require a minimum attendance percentage, commonly 75%, before a student is allowed to sit for semester exams. The rule itself is simple, but the maths behind "how many classes can I still miss" or "how many do I need to attend" trips a lot of students up, mainly because the total number of classes keeps growing as the semester continues.

Why the numbers keep shifting

Attendance percentage is always classes attended divided by total classes held so far — and both numbers change every single day new classes happen. This is exactly why "I can skip 5 more classes" calculated today might not hold true two weeks from now, once more classes have been added to the total.

How many classes you can safely skip

To stay at or above your target percentage while skipping future classes, the calculation accounts for the fact that every class you skip also increases the total class count, working out the maximum number of upcoming misses your current attendance can absorb before dropping below target.

How many classes you must attend to recover

If you're currently below your target, recovering isn't just a matter of attending every class from here on — it can take several consecutive classes attended before the percentage climbs back to target, since each new class attended raises both the numerator and the total, slowing down how fast the percentage moves.

• Recalculate regularly through the semester rather than relying on a number from weeks ago.
• Check your specific college's attendance policy — some allow a slightly different cutoff or medical exemptions.
• Treat a calculated "safe to skip" number as a buffer, not a target to use up entirely.

Enter your total classes, classes attended, and target percentage, and the calculator instantly shows where you stand along with exactly how many classes you can miss or need to attend.

A word counter looks simple on the surface but actually tracks several different measurements at once — total words, total characters (with and without spaces), sentence count, paragraph count, and an estimated reading time — each useful for a different kind of writing task.

When character count matters more than word count

Platforms with a strict character limit — a tweet-style post, an SMS, or a form field with a hard cap — care about character count, not word count, since two sentences with the same word count can differ significantly in character length depending on word choice.

When word count is what matters

Academic essays, assignments, and articles are almost always specified by word count rather than characters, since it's a more consistent measure of content length across different writing styles. Meeting a minimum or staying under a maximum word count is often a strict requirement worth checking as you write, not only at the end.

How reading time is estimated

Reading time estimates are usually based on an average adult reading speed of roughly 200-250 words per minute for general text, so a 1,000-word article works out to somewhere around four to five minutes — useful context for blog posts or articles where you want to set reader expectations upfront.

• Paste or type your text and the counts update live as you edit.
• Use the sentence and paragraph counts to gauge how dense or broken-up your writing is.
• Check both word and character counts when a platform's limit isn't explicitly stated.

A summarizer condenses a long article, document, or paragraph down to its key points, saving time when you need the gist of something without reading every line — useful for skimming research material, articles, or long reports before deciding whether to read the full text.

What a summary keeps and what it drops

A good summary keeps the central claims, key facts, and conclusions of the original text, while dropping supporting examples, repeated points, and stylistic flourishes that don't change the core meaning. The shorter the summary length you choose, the more aggressively less-essential detail gets trimmed.

When a summary can mislead

Summarizing works best on text with a clear main point — an article, a report, an explanation. It's less reliable on text where nuance and exact wording genuinely matter, such as legal or contractual text, where a shortened version could accidentally drop a qualifying condition that changes the meaning. For anything with legal or financial consequences, always read the full original.

Getting a better summary

• Paste well-structured text (clear paragraphs) rather than a jumbled block for a cleaner result.
• Choose a shorter summary length for a quick skim, or a longer one if you need more of the supporting detail retained.
• Treat the summary as a starting point — for anything important, cross-check against the original text.

Everything is processed locally in your browser, so the text you're summarizing isn't sent off to an external service.

A strong password isn't about being clever with substitutions like "P@ssw0rd" — attackers' cracking tools already account for common substitutions. What actually matters is length and genuine randomness, since both make the number of possible combinations an attacker would have to try astronomically larger.

Length beats complexity rules

A long, random password of 16+ characters is generally far stronger than a shorter password crammed with symbols, because each additional character multiplies the total number of possible combinations. Many sites still enforce arbitrary complexity rules (at least one uppercase, one number, one symbol), but length is the single factor that matters most for resisting brute-force attacks.

Why reused passwords are the real risk

Even a genuinely strong password becomes a liability if it's reused across multiple accounts — a single data breach on one unrelated website can expose a password that then unlocks every other account where you reused it. Using a different, randomly generated password for every account contains the damage from any single breach.

Practical tips

• Use at least 16 characters where a site allows it, mixing letters, numbers and symbols.
• Never reuse the same password across more than one account.
• Store generated passwords in a password manager rather than trying to memorize dozens of random strings.
• Turn on two-factor authentication wherever it's available, as a second layer beyond the password itself.

The generator creates a random string directly in your browser using your device's own randomness source — nothing you generate is transmitted or logged anywhere.

The classic meme format — bold white text with a black outline, top and bottom of an image — has stayed popular because it's instantly readable at any size, which matters since most memes are viewed as small thumbnails scrolling past in a feed rather than full-screen.

Keeping text short and readable

Meme text works best short — a single punchy line at the top and bottom, rather than a paragraph crammed into the frame. Long text shrinks to fit the image width, which quickly becomes unreadable at the small sizes memes are usually viewed at on a phone screen.

Picking the right image

A meme's humor usually comes from the mismatch between the image's original context and the new text placed over it — an image with a clearly readable, expressive face or reaction generally works better as a template than a busy, cluttered photo where the added text competes visually with the background.

Quick tips

• Keep both text lines roughly balanced in length so the layout looks even.
• Use the classic bold white-with-black-outline text for maximum readability against any background.
• Preview at a small size before sharing — if it's hard to read as a thumbnail, shorten the text.

The image and text are composited together directly in your browser, so you can preview and re-edit the wording as many times as you like before downloading the final image.

Working out age in years, months, and days by hand seems simple until you hit a birth month that hasn't occurred yet this year, or a leap year in the mix — both of which trip up manual subtraction more often than people expect.

Where manual calculations go wrong

If today's date falls before your birthday this year, you have to "borrow" from the year calculation, similar to borrowing in subtraction — get this wrong and you'll be off by exactly one year. Leap years add another wrinkle, since February has an extra day roughly once every four years, which shifts day counts if a leap day falls within the range you're calculating.

What an exact age calculation gives you

Beyond just a birthday countdown, exact age in years, months and days is genuinely required for things like eligibility checks (a minimum age for a competitive exam or a specific age cutoff for admission), or simply satisfying curiosity about precisely how long you've been alive down to the day.

Common uses

• Checking eligibility for exams, scholarships, or government schemes with a specific age cutoff.
• Working out exact age difference between two people or two dates.
• Finding out exactly how many days until your next birthday.

Enter your date of birth and today's date (or any target date), and the calculator handles the leap-year and month-length edge cases automatically.

Percentages come up constantly — discounts, exam marks, tips, salary hikes — but a few specific percentage calculations trip people up more than the basic "what is X% of Y" case, mostly around percentage change and reversing a percentage back to an original value.

Percentage of a number

The simplest case: to find X% of Y, multiply Y by X and divide by 100. For example, 18% of ₹1,500 is 1500 × 18 ÷ 100 = ₹270. This is the calculation behind discounts, tax additions, and marks scored out of a total.

Percentage change (increase or decrease)

To find the percentage change between two numbers, subtract the original value from the new value, divide that difference by the original value, then multiply by 100. Get the order of subtraction wrong and you'll get the right magnitude but the wrong sign — mixing up an increase for a decrease.

Working backward from a percentage

If you know a discounted price and the discount percentage, finding the original price isn't as simple as adding the percentage back — you need to divide the discounted price by (1 − discount as a decimal). A price of ₹800 after a 20% discount comes from an original of 800 ÷ 0.8 = ₹1,000, not 800 + 20% of 800.

• Use "percentage of a number" for discounts, tax, and marks calculations.
• Use "percentage change" to compare an old value to a new one, like a salary hike or a price change.
• Use "reverse percentage" to recover an original value from a discounted or increased amount.

Text case isn't just a stylistic choice — different contexts have real conventions around it, from programming variable names to title formatting in an article, and getting it wrong can look inconsistent or even break code that expects a specific naming convention.

Common case styles and where they belong

• Sentence case — only the first word and proper nouns capitalized — is standard for regular prose and most UI labels.
• Title Case — Every Major Word Capitalized — is common for headlines, book titles, and section headings.
• UPPERCASE is used sparingly, usually for emphasis, acronyms, or short warning labels — long stretches of uppercase text are harder to read and can come across as shouting.
• camelCase and snake_case are programming conventions for variable and function names, chosen based on the language or style guide a codebase follows.

Why manual retyping introduces errors

Manually retyping a block of text just to change its case is slow and easy to get wrong, especially with longer paragraphs, since it's easy to accidentally alter words or punctuation while retyping rather than just reformatting the case.

Practical uses

Converting a title someone pasted in all caps down to proper title case, cleaning up variable names when switching between programming naming conventions, or converting a paragraph to sentence case after copying it from a source that used a different formatting style throughout.

Paste your text, choose the case style you need, and the conversion happens instantly without altering anything except the letter casing itself.

Renaming a handful of files one at a time is manageable, but a folder of a hundred photos or documents that all need a consistent naming pattern quickly becomes tedious to do by hand — which is exactly the problem batch renaming solves.

Common batch renaming patterns

• Adding a sequential number to a set of files — photo-001, photo-002, photo-003 — so they sort in the right order.
• Prefixing or suffixing every file with a common label, like a project name or a date.
• Find-and-replace across all filenames at once, useful for fixing a typo or an outdated label that appears in many file names.
• Stripping unwanted characters — spaces, special symbols — that some systems or upload forms don't accept in filenames.

Why consistent naming actually matters

Files named consistently sort correctly, are easier to search for later, and avoid the ambiguity of generic names like "IMG_2043" or "Untitled document (3)" that give no clue what's inside without opening each one individually.

A few tips before renaming in bulk

Preview the new names before applying the batch rename, since a pattern mistake applied across dozens of files is easy to make and time-consuming to undo file by file. Avoid special characters that some operating systems or upload systems reject, like slashes or colons, in the naming pattern you choose.

Select your files, define the renaming pattern once, and the tool applies it consistently across every file in the batch.

Converting typed text into a handwriting-style image is popular for making assignment notes look handwritten, creating personalized notes and letters, or simply saving time compared to writing out a long passage by hand while still keeping a handwritten look for a class or personal project.

Choosing a font that looks natural

Handwriting-style fonts vary a lot in how convincing they look — some closely mimic natural pen strokes and slight irregularities, while others look more clearly computer-generated. Picking a font that matches the tone you want (a neat, careful hand vs. a quicker, more casual scrawl) makes a real difference to how natural the final page looks.

Paper style and layout

Matching the background to ruled notebook paper, plain white paper, or graph paper — whichever fits your use case — along with realistic margins and line spacing, helps the final image read as a genuinely handwritten page rather than an obviously templated one.

Tips for a convincing result

• Choose a font and ink color combination that matches how you'd naturally write by hand.
• Keep line spacing and margins close to a real notebook page rather than uniform machine spacing.
• Break very long text into multiple pages rather than shrinking the font to fit everything onto one.

Type or paste your text, choose a handwriting style and paper background, and the tool renders the page as a downloadable image.

Most budgeting struggles aren't about lacking a plan — they're about not tracking where money actually goes each month. A monthly expense tracker closes that gap by recording income and spending by category, so patterns that are easy to miss in the moment become obvious when you look at the full month together.

The needs, wants, savings split

A common and simple way to structure a budget is splitting spending into needs (rent, groceries, bills — things you genuinely can't avoid), wants (dining out, entertainment, non-essential shopping), and savings (money set aside rather than spent). Seeing this split as a percentage of income, rather than just a list of numbers, makes it much easier to spot when "wants" spending has quietly crept up.

Why category-wise tracking beats a single total

Knowing you spent ₹40,000 this month tells you little on its own; knowing that ₹12,000 of it went to food delivery tells you exactly where to look if you want to cut back. Breaking expenses into categories turns a vague sense of "I'm spending too much" into a specific, actionable target.

Setting a savings goal

A savings goal with a target amount gives tracking a purpose beyond just recording numbers — seeing progress toward a specific target, and an estimate of how many months it'll take at your current savings pace, makes consistent saving feel more concrete than an open-ended "save more" intention.

• Log income and every expense as it happens, rather than trying to reconstruct the month from memory later.
• Review the needs/wants/savings breakdown at the end of each month, not just the total spent.
• Set a realistic savings goal and check your pace regularly rather than only at the end.

All your entries are saved locally in your browser for each month, so you can flip back through previous months' breakdowns without any account or sign-up.

A good name is short enough to remember, easy to say out loud, and gives at least a hint of what the business, channel or app is about — but it doesn't have to describe everything literally, since some of the most recognisable brands use invented or unrelated words.

What to check before you commit

• Say it out loud — if people are likely to mishear or misspell it, that's friction you'll deal with forever.
• Check domain and handle availability on the platforms that matter most to you before falling in love with a name.
• Search the name plus your industry to see if another business is already using something close to it.
• Keep a shortlist of 3-5 favourites rather than deciding on the first idea that sounds good.

Why keyword-based generation works

Starting from a keyword tied to your niche keeps every suggestion relevant, while mixing in prefixes, suffixes and style-based words gives you variety without wandering completely off-topic. Generating multiple rounds and comparing batches side by side usually surfaces better options than staring at a blank page.

Enter your keyword, choose a category and style above, and generate as many rounds as you need until something clicks.

A password on a PDF is a simple way to keep sensitive documents — contracts, payslips, ID scans — from being opened by anyone who doesn't have the password, without needing any special software to view it once unlocked.

What "Protect PDF" does

It encrypts your file with the password you choose, using standard PDF encryption that any PDF reader will recognise — the file will prompt for that password before it opens.

What "Remove Password" does

Since removing an existing password means fully decrypting the file, this tool opens the PDF using the password you provide and rebuilds a new, unlocked PDF from it page by page. The layout and content look the same, but the rebuilt file is image-based, so any selectable text in the original won't be selectable in the output.

Both directions run entirely in your browser — your file and password are never uploaded anywhere.

A PDF freezes exactly what the reader sees — no accidental edits, no formula errors from a different spreadsheet app, and consistent formatting across every device, which makes it the safer format for sharing a finished report, invoice-style sheet, or data export with someone outside your team.

What happens to formulas and formatting

The values currently shown in each cell are converted into a table, so calculated results carry over correctly, while the underlying formulas themselves are not preserved in the PDF, since a PDF is a fixed, non-editable format by design.

Multiple sheets

Every sheet in the workbook is converted in order and separated onto its own set of pages, with the sheet name shown as a heading, so a multi-tab workbook stays organised in the final PDF.

Base64 is a way of representing binary data — like an image, font or file — using only 64 printable text characters (A-Z, a-z, 0-9, + and /). It's used everywhere text-only formats need to carry binary-ish data: embedding small images directly in CSS or HTML, attaching files in emails, or passing data safely inside a JSON payload or URL.

Base64 is not encryption

A common misconception is that Base64 hides or protects data — it doesn't. It's purely an encoding scheme, and anyone can decode it back to the original instantly. It should never be relied on for security or privacy; use real encryption for that.

Why the string looks longer than the original

Base64 encoding increases the size of the data by roughly a third, since it maps every 3 bytes of binary data into 4 text characters — a trade-off worth knowing if you're embedding a large image directly as Base64 rather than linking to a file.

• Use "Image → Base64" to get a data URL you can paste directly into CSS, HTML, or an API payload.
• Use "Base64 → Image" to turn a data URL or raw Base64 string back into a downloadable image file.
• The text mode correctly handles emoji and non-English characters using UTF-8 before encoding.

The same colour can be written three common ways: HEX (like #00B89A), RGB (like rgb(0, 184, 154)), or HSL (like hsl(170, 100%, 36%)) — all describe the identical colour, just in different formats suited to different tools.

HEX — the web design standard

HEX codes are the most common format in CSS, design tools and image editors, since they're compact and easy to paste around. Each pair of characters represents red, green and blue intensity from 00 to FF.

RGB — closer to how screens actually work

RGB expresses the same red, green and blue channels as plain 0-255 numbers, which maps directly to how a screen's pixels are lit, making it useful when working with code that manipulates colour values numerically.

HSL — the easiest to reason about

HSL (Hue, Saturation, Lightness) is often the most intuitive for adjusting a colour by feel — keeping hue fixed and sliding lightness gives you tints and shades of the same colour without recalculating RGB values by hand.

Extracting a palette from an image

A dominant-colour palette groups similar pixel colours together and returns the most frequent ones — handy for pulling a brand palette out of a logo, or picking complementary colours out of a photo for a design.

Sideways or upside-down pages are almost always a scanning problem — a document fed into a scanner in landscape orientation, or a mixed-orientation batch that gets exported without correcting page rotation along the way.

Per-page vs whole-document rotation

Rotating the entire document works when every page has the same problem, which is common with scans. Mixed documents — where some pages are portrait and others landscape — need each affected page rotated individually instead, which is why per-page controls matter alongside a rotate-all shortcut.

What actually changes

Rotating a PDF page only updates its orientation metadata — the text and images inside the page are not re-rendered or recompressed, so there's no loss in quality or resolution from rotating.

• Use "Rotate All" first if the whole scan came in sideways.
• Then fine-tune any individual pages that still look wrong.
• Preview thumbnails update live so you can confirm orientation before downloading.

A favicon isn't one file — different browsers, home-screen shortcuts and bookmark tiles each ask for a different pixel size, so a properly set-up site ships several versions of the same icon rather than a single image stretched to fit.

What each size is actually for

The tiny 16×16 and 32×32 versions show up in browser tabs and bookmark bars, where every pixel counts — fine detail and small text simply disappear at that size. The 180×180 version is what iOS uses when someone adds your site to their home screen, while 192×192 and 512×512 cover Android home-screen icons and the icon shown while a progressive web app is loading.

Designing an icon that survives shrinking

• Start from a square, high-contrast mark rather than a full logo with a wordmark — text usually becomes unreadable below 48px.
• Leave a little padding around the edges so the icon doesn't look cropped once browsers round its corners.
• Check the 16px preview specifically — if it reads as a blob, simplify the artwork further.

Upload your image once and this tool renders every required size side by side, so you can judge how the icon actually holds up before generating the final ICO, PNG set and manifest.

Photos end up sideways for a very ordinary reason: phones and cameras record which way was "up" when the shutter clicked, and not every app that later opens the file reads that orientation tag correctly — so the same photo can look upright in one app and sideways in another.

When to rotate

Rotating in 90° steps is the fix for a photo taken with the camera turned sideways or upside down. Since the turn is always a right angle, nothing in the image is distorted or resampled — pixels simply move to a new position.

When to flip instead

Flipping mirrors an image left-to-right or top-to-bottom, which is different from rotating. It's the right fix for a front-facing camera or webcam shot where text or logos appear backwards, or for a scan that was fed into the scanner face-down.

• Sideways or upside-down photo → rotate left or right.
• Mirrored text or a backwards logo → flip horizontal.
• A scan that came out upside-down top-to-bottom → flip vertical, or rotate 180°.

Every transform in this tool runs on an HTML canvas element in your browser, so you can stack a rotation and a flip and preview the exact result before downloading.

A Systematic Investment Plan (SIP) is a fixed amount invested into a mutual fund every month, rather than investing a large sum once. The maturity value depends on three things: how much you invest each month, the rate of return the fund earns, and how long the money stays invested.

Why time matters more than the amount

Because returns compound month over month, the number of years invested tends to affect the final corpus far more than modest increases in the monthly amount — money invested early has many more compounding cycles ahead of it than money invested later, even at the same monthly amount and rate.

SIP vs lumpsum

A lumpsum investment grows on the full amount from day one, which can outperform a SIP of the same total size if markets rise steadily. A SIP instead spreads purchases across many months, which averages out the price paid across market ups and downs — a smoother, lower-stress way to invest for most people who don't want to time the market.

• A higher expected return rate assumption produces a larger projected corpus — but returns aren't guaranteed, so it's worth checking the estimate at a few different rates.
• A longer tenure lets compounding do more of the work, often more than a larger monthly amount over a shorter period.
• The "invested amount" figure is simply monthly amount × number of months — everything above that is projected growth.

Enter your numbers above to see the estimated maturity value, your total contribution, and the projected wealth gained, side by side.

Since Budget 2025, the new tax regime taxes income up to ₹4 lakh at nil, then 5% up to ₹8 lakh, 10% up to ₹12 lakh, 15% up to ₹16 lakh, 20% up to ₹20 lakh, 25% up to ₹24 lakh, and 30% beyond that — combined with a Section 87A rebate of up to ₹60,000 that makes net taxable income up to ₹12 lakh effectively tax-free.

Why the new regime usually wins without deductions

The new regime's slabs are wider and its rates lower at every level compared to the old regime's ₹2.5 lakh / ₹5 lakh / ₹10 lakh structure — but it only allows a standard deduction (₹75,000 for salaried taxpayers and pensioners) and a few narrow exceptions, with no 80C, 80D, HRA or home loan interest deduction on a self-occupied property.

When the old regime still comes out ahead

The old regime becomes competitive once your deductions add up: ₹1.5 lakh under 80C, up to ₹50,000 more under NPS 80CCD(1B), a health insurance premium under 80D, HRA if you pay rent, and up to ₹2 lakh of home loan interest on a self-occupied property. Stack several of these together and the old regime's lower taxable income can outweigh its higher rates.

• Little to no deductions, or renting without HRA in your salary structure → the new regime usually wins.
• Home loan + 80C + NPS + 80D all in use → run both numbers, since the old regime can pull ahead.
• Marginal relief smooths the edge just above the ₹12 lakh new-regime threshold, so a small rise in income there doesn't cause a disproportionate tax jump.

Enter your income and deductions above to see the exact tax under each regime, slab by slab, rather than relying on rules of thumb.

A Fixed Deposit locks in a lump sum for a fixed tenure at a fixed rate, while a Recurring Deposit lets you build up a deposit through equal monthly instalments — both are commonly used by Indian savers who want guaranteed, low-risk returns rather than market-linked ones.

Why compounding frequency matters for FDs

Most Indian banks compound FD interest quarterly, which yields slightly more than yearly compounding at the same nominal rate, since interest itself starts earning interest sooner. Comparing FDs at different compounding frequencies is one of the easiest ways to catch a marginally better real return.

RD maturity isn't a simple multiplication

Because each monthly instalment sits in the bank for a different length of time, an RD's maturity value isn't just monthly deposit × months — the earliest instalments earn interest for close to the full tenure, while the last one barely earns any, which is exactly what the quarterly-compounding RD formula accounts for.

• FDs suit a lump sum you already have and don't need soon.
• RDs suit disciplined monthly saving when you don't have a lump sum upfront.
• Breaking an FD or RD early usually reduces the effective interest rate — check your bank's premature withdrawal terms first.

Tipping norms vary a lot by country and even by city, but the underlying maths is always the same: take a percentage of the bill as the tip, add it to the original amount, then divide by however many people are sharing the cost.

Tipping in India

Tipping isn't as strictly expected in India as in some other countries, but 10% has become a common informal norm at sit-down restaurants, especially in cities — many restaurants also add a discretionary service charge to the bill already, which is worth checking before adding a tip on top.

Splitting evenly vs splitting by order

This calculator assumes an even split, which works well for a shared meal where everyone roughly ate the same amount. If one person ordered significantly more than others, an itemised split — where each person pays for exactly what they had, plus their share of the tip — is fairer, though it takes a bit more working out.

Your Basal Metabolic Rate is the energy your body burns just to keep you alive — breathing, circulation, cell repair — before you've moved a muscle. It's the biggest single chunk of most people's daily calorie burn, which is why it's the starting point for any calorie target.

From BMR to TDEE

TDEE adds in everything else: walking around, exercise, even fidgeting. Multiplying BMR by an activity factor is a rough but widely used way to estimate this, since actually measuring daily energy expenditure needs specialised lab equipment most people don't have access to.

Turning TDEE into a target

• Eating at TDEE roughly maintains your current weight.
• A deficit of ~500 kcal/day is a commonly used moderate rate for gradual fat loss.
• A surplus of ~500 kcal/day supports gradual, controlled weight gain.
• Very large deficits or surpluses are harder to sustain and are best planned with professional guidance.

Treat the numbers here as a starting estimate — actual results depend on individual metabolism, sleep, stress and many other factors, so it's worth adjusting based on how your weight actually trends over a few weeks.
