WebP Compressor
Compress
The canvas previews the compressed result live as you adjust the settings. Click Compress for the exact size and a before/after split — drag the divider to judge the quality, then download. The original file is never modified.

WebP is already the most efficient mainstream web format, but WebP files exported by design tools are often still 30–50% larger than necessary. Re-compress them here with precise quality control, entirely in your browser, and keep the transparency WebP is known for.
How to use the webp compressor
- Add your WebP files by drag-and-drop or the file picker.
- Adjust quality. WebP holds up visibly better than JPG at low settings.
- Review the new size and preview quality for each file.
- Download files individually or all together as a ZIP.
Frequently asked questions
Why re-compress a format that is already efficient?
Export tools often default to conservative settings (quality 90+) or skip the tuning that squeezing the last kilobytes requires. Re-encoding at quality 75–80 frequently removes 30%+ with no perceptible change, because WebP degrades gracefully.
Does WebP support transparency?
Yes. WebP has a full alpha channel, and this compressor preserves it. That combination of small size plus transparency is exactly why WebP has become the default format for modern websites.
Which browsers support WebP?
Every browser released since around 2020: Chrome, Edge, Firefox, Safari (14+), Opera, and mobile equivalents. If you need to support genuinely ancient browsers, keep a JPG fallback. Our converter pages handle that.
