About this image compressor
Reduce the file size of your images while keeping the same format — a JPEG stays a JPEG, a PNG stays a PNG. Everything happens locally: your files are re-encoded and downloaded right in the browser, so nothing is ever uploaded to a server. Add up to 10 images, choose a quality level, and download them one by one or all together as a ZIP.
100% in-browser
Images are compressed on your device with the Canvas API and WebAssembly encoders — never uploaded.
Keeps the format
JPEG, WebP and AVIF are re-encoded at your chosen quality; PNG is optimised losslessly with oxipng.
Never larger
If compression wouldn't help, the original is kept — you'll never download a bigger file.
Lossy vs lossless
- JPEG, WebP & AVIF — lossy: lowering the quality slider drops detail you usually can't see for big size savings.
- PNG — optimised losslessly: pixels are untouched, so the savings depend on how unoptimised the file was.
- Tip — for the smallest files, also try the WebP & AVIF converter to switch to a more efficient format.
