PNG optimization is lossless. JPEG and WebP quality is adjustable. Files are processed for this request and are not stored by this tool.
Tune an existing WebP
WebP is already a compact web format, but exported files can still be heavier than necessary. Recompression is useful when an image was saved at a very high quality or came from a generic converter.
Good for modern web assets
WebP works well for many photographs and graphics used on websites. Smaller assets can reduce transfer size, especially on pages that display many images.
Keep dimensions unchanged
This page changes encoding quality, not width or height. Use the dedicated resizer if you also need to reduce pixel dimensions.
Questions about compress webp online
Will WebP compression remove transparency?
No. WebP can support alpha transparency and the compressor keeps the WebP format.
Why might savings be small?
A WebP that was already efficiently compressed may have little redundant data left. In that case ImageCarpenter avoids returning a larger result.
