Compress WebP images fast.
Make existing WebP images lighter with quality and resize controls.
WebP is already optimized, but resizing or lowering quality can still reduce size.
JPG, PNG and WebP stay in their format. Other inputs become WebP.

How WebP Compressor works
Files are validated, decoded, resized when requested, and encoded by your browser. The application does not send image files to a server, and animated inputs are rejected instead of silently losing frames.
Optimize an existing WebP without unnecessary changes
WebP is often already compact. Recompressing it at a lower quality can reduce size, but repeated lossy encoding can also soften detail. Work from the highest-quality source available and inspect the result before replacing it.
The default keeps WebP output and the original dimensions. If a same-size WebP would become larger, the original file is retained. For bigger savings, set the maximum width to match where the image will be displayed. Animated WebP is rejected; only static images are supported.
