Compress JPEG images in your browser. We detect your file's original chroma sampling and never downgrade it. No upload, no quality loss beyond what you choose.
How it works
Everything on this site runs inside your browser. The image processing is done by WebAssembly modules downloaded with the page, so your files are read from your device, processed on your device, and never transmitted anywhere.
How this is paid for
The tools are free and there is no account to create. Hosting is paid for by advertising, which is why you will see some ads on the page. We do not sell or share your files — we never receive them.
Privacy
No file ever leaves your device, so there is nothing for us to store, log, or lose. Privacy
