What is Squoosh?
Squoosh is a web app for making images smaller without wrecking their quality. Drop in a photo and you see the original and the compressed version side by side, with a slider to compare them and the new file size updating as you change settings. You can pick from codecs like MozJPEG, WebP, AVIF, OxiPNG, JPEG XL and QOI, then tune quality and advanced options.
It was built by Google Chrome Labs and the source is on GitHub. All compression happens locally in your browser, so your images are never sent to a server, and the app works offline once it has loaded. Squoosh can also resize an image and reduce its color palette before compressing, which makes it handy for preparing pictures for websites, emails and blog posts.
