Compress WebP online — reduce file size
Already on WebP but still too big? Dial quality down a notch, check the preview, download. WebP is usually smaller than JPG at similar look, but high export settings or huge dimensions can still land you in multi-megabyte territory. This page is for that second pass on web assets.

WebP supports lossy compression and transparency, so it shows up everywhere in modern sites. If your build pipeline or design tool exported at high quality, files can still be chunky — this page trims that extra fat.
Re-crushing an already lossy WebP hard will stack artifacts. When you still have a PNG, JPG, or high-quality master, converting fresh to WebP often beats squeezing a tired file again.
If the target platform rejects WebP, switch to JPG or PNG instead of compressing WebP further.
How to re-compress WebP
- Upload WebP
- Lower quality and check the preview
- Balance size vs. clarity
- Download the optimized WebP
When to use the WebP page
- Your library is already WebP and you only need another size cut.
- Avoid accidentally picking PNG on a generic page and bouncing file size up.
- Preview helps fine-tune hero images tied to page load.
Scenarios
- Static site WebP still over your performance budget
- Replacing older CDN WebP files one at a time with smaller versions
- Slightly oversized transparent WebP icons
Tips
- Drop quality in small steps; watch text edges for blur.
- Semi-transparent edges suffer first on transparent WebP.
- If savings are tiny, stop — maybe resize instead.

Compress WebP FAQ
- Can I convert to JPG here?
- This page keeps WebP output. Use image conversion or the general compressor for other formats.
- Will transparency disappear?
- Staying on WebP usually preserves it. Converting to JPG elsewhere removes it.
- Why does nothing shrink?
- Quality may already be low, or the image is very detailed. Try resizing.
