About the image compressor
An image compressor makes a photo smaller in file size while keeping it usable on screen. Drop a JPEG, PNG, or WebP, choose a quality level, and get a lighter file you can email, attach, or upload without hitting a size cap — most camera photos shrink by 60–90% with no visible difference.
Compression runs in your browser using the same canvas engine that draws this page, so the image is never uploaded to a server. Switch the output to WebP for the smallest file, JPEG for the widest compatibility, or PNG when you need the pixels back untouched.
How to compress an image
- 1
Drop an image
Pick or drag a JPEG, PNG, or WebP. It loads straight into the page — there's no upload step.

Choose format and quality
JPEG, PNG, or WebP, from Best down to Aggressive. The preview and the new file size update with every change.

Download the smaller file
Save the result and see exactly how much smaller it is than the original.
