About Squoosh

Developed by the Google Chrome team, Squoosh is a privacy-first web application. Because it utilizes WebAssembly codecs (MozJPEG, OxiPNG, WebP, AVIF, QOI), all image processing happens on your local device—no images are uploaded to external servers. It features an interactive before/after visual slider to inspect compression artifacts in real time.

Best for: Developers and perfectionist designers wanting complete control over compression codecs and 100% offline privacy.
