Squoosh is a free, open-source image compression tool from Google Chrome Labs. Supports AVIF, WebP, MozJPEG, OxiPNG and more, with real-time side-by-side quality comparison, all processed locally in the browser or via a desktop app.
Completely free, no account or sign-up required, open source.
Developers and designers who want fine-grained control over compression format and quality settings with an immediate visual before/after comparison, without any cost or account.
All processing happens locally on-device (browser or desktop app): images never leave your machine, a genuine privacy advantage over server-based compressors.
