Squoosh

Squoosh is a browser-based image compressor from Google Chrome Labs that runs entirely client-side — drag in a PNG, adjust the quality slider, compare original vs compressed in a split view, and download in WebP, AVIF, JPEG-XL, or MozJPEG. Your images never leave your browser.

TinyPNG is the popular alternative but uploads to a server and limits free usage. Sharp (Node.js) is the programmatic option for build pipelines. ImageMagick is the CLI classic.

The catch: Squoosh processes one image at a time — no batch processing. The open-source repo hasn't seen major updates recently. For automated image optimization in a build pipeline, you need Sharp or @squoosh/lib (which is deprecated). Squoosh is a manual tool for quick one-off optimizations, not a production pipeline component.
