About Squoosh

Squoosh is a browser-based image compression tool that reduces file size while allowing users to inspect quality differences before saving. Users can open an image, adjust compression settings, and export a smaller version, with support for dropping, pasting, or selecting sample images to test.

All image processing happens locally on the user's device rather than being uploaded to a server, so images do not leave the device during compression. The tool requires JavaScript to run in the browser. Source code for the project is available on GitHub.
