Lighter pages, same look
WebP generally compresses photos more efficiently than JPG, so you get smaller files at a comparable quality — which means faster page loads and less bandwidth.

Pick the quality with a slider and convert as many files as you like. Encoding happens locally with WebAssembly; no upload, no limits.
