FAQ

Image Compressor — frequently asked questions

Does compressing reduce image resolution?+

No, this tool reduces file size by adjusting compression quality, not the pixel dimensions of your image. Use the Image Resizer if you also want to change dimensions.

What is the difference between Low, Medium and High compression?+

Low compression keeps maximum quality with a smaller file size reduction, while High compression saves more space with a slightly softer image. Medium offers a balanced result for most uses.

Is there a limit to how many images I can compress?+

No. You can upload and compress as many images as you like, one at a time or in batches.

Do you store or see my uploaded images?+

Never. Compression runs locally in your browser using the Canvas API — your images are never transmitted anywhere.

About

Built for fast, private image editing

ZynPix started from a simple frustration: most online image tools force you to upload personal photos to an unknown server just to shrink a file or change its dimensions. We wanted something faster and more private.

What we do

ZynPix offers two focused, free utilities — an Image Compressor and an Image Resizer — that run entirely inside your browser using JavaScript and the Canvas API. No accounts, no uploads, no waiting.

Our principles

  • Privacy first: your files never leave your device.
  • No clutter: every tool does one job, well.
  • Free forever: no paywalls or hidden limits on core features.
