What is Squoosh?

Squoosh is a free, open-source image compression web app built by Google Chrome Labs. It lets users drag and drop or paste an image, then compare compression settings side by side before downloading the optimized result, entirely inside the browser. Because all processing runs locally using WebAssembly-based codecs, images never leave the user's device, which the project highlights as a core privacy feature. The source code is published on GitHub under the GoogleChromeLabs organization.
