Image Compressor
Compress JPEG, PNG and WebP images with a quality slider, right in your browser. Batch several files, preview before and after, convert between formats. Nothing is uploaded — unlike services that send your images to a server.

Why compress in the browser?
Most online image compressors upload your files to a server, process them, and send them back. For screenshots, ID photos, contracts or product shots, that means your images sit on someone else's machine. This tool uses the browser's Canvas API: the image is decoded, re-encoded at your chosen quality, and handed straight back. No upload, no account, no queue.
JPEG, WebP and PNG
- JPEG / WebP: lossy: the quality slider trades visual fidelity for size, and WebP is usually smaller than JPEG at the same quality.
- PNG: lossless, so the quality slider has little effect. To shrink a PNG photo significantly, convert it to JPEG or WebP using the Output selector.
