This tool converts your images to the WebP format entirely within your browser. Here is what you should know:
- 100% Local — Your images never leave your device. There are no server uploads, no APIs, no cloud processing. Everything runs in your browser using the built-in Canvas API.
- Transparency Preserved — PNG images with alpha channels (transparency) retain their transparency when converted to WebP.
- Quality Control — Adjust the quality slider to find the right balance between file size and visual fidelity. Lower quality means smaller files.
- Batch Processing — Drop multiple files at once. Convert them all and download individually or as a single ZIP file.
- Animated GIFs — Note: Browser Canvas API only captures the first frame of animated GIFs. Animated output is not currently supported.
- Memory Safe — Object URLs are automatically revoked after downloads to prevent memory leaks. Large files (50MB+) will trigger a warning but will still be processed.
Supported input formats: PNG, JPG/JPEG, GIF, BMP, TIFF, SVG, AVIF, ICO
