WebP Converter
Convert images to and from WebP format.
Processed entirely in your browser. Your image is never uploaded to a server.
- Both directions: to WebP for the web, or back to JPG/PNG for compatibility.
- An explicit quality slider, not a fixed compression level — tune the size/quality tradeoff yourself.
- Lossless mode for WebP maxes out quality for icons, screenshots and hard-edged graphics where lossy artifacts are visible.
- Convert up to 40 images at once and download them as a ZIP.
- WebP is typically 25–35% smaller than JPG at similar quality.
- Runs in your browser — images are never uploaded.
Why this is private
- Processed entirely in your browser. Your image is never uploaded to a server.
- Open your browser's DevTools → Network tab while using this tool — you won't see a request carrying your input, because it never leaves your device.
- Nothing you enter is uploaded to a server or shared with us — the processing happens entirely on your device.
