About Compress WebP

Reduce the file size of your WebP images without a round-trip to a server. Drop in a WebP, pick a quality level, and we re-encode it locally with the same Squoosh codecs that power Google's image tool. The output stays a WebP — just smaller — with transparency preserved.

Everything runs in your browser tab via WebAssembly. Your images never leave your device, which makes this safe for graphics, screenshots, and anything else you'd rather not hand to a cloud service.
