Image Compressor

Compress PNG, JPG, and WebP images without changing format. Privacy-preserving — runs in your browser, not on a server.

Compression

01 — Overview

How it works

Shrink image file sizes while keeping the format the same. Uses MozJPEG for JPG, OxiPNG for lossless PNG optimization, and libwebp for WebP. Drop your images, choose a strength level, and download the optimized versions with per-file before/after stats. Unlike TinyPNG or similar tools, nothing uploads — your images stay on your device.

04 — FAQ

Frequently asked

Same kind of result — significantly smaller files at minimal quality cost. Two differences: nothing uploads (TinyPNG sends your files to their server), and there's no monthly file-count limit. The trade-off is that very large batches can take longer than a server-side service because all the work happens in your browser.
