About JPG to WebP

Convert JPG photos to WebP, Google's modern format that's typically 25–35% smaller at the same visual quality. Pick a quality level and we re-encode your JPG locally, so pages load faster without a visible drop in clarity.

The re-encode runs entirely in your browser with WebAssembly codecs. Your photo never leaves your device, so even sensitive images stay private.
