This tool needs JavaScript, because compression runs on your device rather than on a server.
WebP is already the most efficient widely-supported image format, so compressing it further is about trimming a file that is close to optimal rather than fixing something bloated. It still helps: WebP exported at maximum quality from a design tool often carries far more data than a web page needs. Transparency is preserved throughout, which is the main reason to stay in WebP rather than moving to JPG.
Worth knowing: Because WebP compresses so well already, expect more modest savings than you would see from a JPG or a PNG.
Worth knowing: Transparency survives compression here. Converting to JPG would flatten it to a solid colour.
How to compress WebP files
- Add your files. Choose or drop as many WebP files as you like.
- Pick quality or a target size. Quality mode gives you direct control; target size mode meets a hard limit in KB or MB.
- Download. Take files individually or all at once as a ZIP.

Common questions
Is it worth compressing a WebP file?
It depends where it came from. A WebP exported at maximum quality from Figma or Photoshop usually has plenty of headroom. A WebP already served by an optimised website is probably close to as small as it usefully gets.
Does compressing WebP keep transparency?
Yes. WebP has a full alpha channel and it is preserved through compression.
Can I set an exact target size?
Yes — switch to target size mode and enter a figure in KB or MB. The tool searches quality levels to find the best one that fits.
