Squoosh is a web-based image compression tool made by Google Chrome Labs. Because it runs codecs compiled to WebAssembly inside the browser, images are processed locally without being uploaded to a server, and you can compare quality and file size while viewing the compressed result in various formats such as MozJPEG, WebP, AVIF, and OxiPNG side by side with the original. It was also provided as a CLI and library for use from the command line and Node.js.
