Compress WebP Online for Free
WebP is already one of the more efficient image formats around, but that doesn't mean every WebP file is as small as it could be — images exported at high quality settings, or ones carrying more detail than a page actually needs, can still be trimmed down significantly. This tool re-compresses WebP files directly in your browser, squeezing out extra file size for faster page loads and lighter storage.

Compress WebP Online for Free
WebP is already one of the more efficient image formats around, but that doesn't mean every WebP file is as small as it could be — images exported at high quality settings, or ones carrying more detail than a page actually needs, can still be trimmed down significantly. This tool re-compresses WebP files directly in your browser, squeezing out extra file size for faster page loads and lighter storage.
Because WebP supports both transparency and photographic detail well, this tool preserves your image's alpha channel while re-encoding the pixel data at your chosen quality level. Use the slider to balance size against sharpness, or set a target size in MB if you need to hit a specific limit, such as a CDN asset budget or a marketplace's upload cap. For most web graphics, even a modest reduction in quality can shave off a meaningful chunk of file size.
Compression happens locally via the Canvas API, so nothing is uploaded and your file never leaves your device. You can compress a single WebP or drop in a whole batch — each file is handled independently and, when there's more than one, they're bundled into a single zip for download. There's no sign-up, no daily cap, and no watermark added to your images.
Common questions
Yes — WebP is efficient compared to older formats, but files exported at high quality or from certain editing tools still carry more data than necessary for most uses. Re-compressing at a lower quality setting or target size can shrink them further.
No, the alpha (transparency) channel is preserved throughout compression. Only the visible pixel data is re-encoded at a smaller size; transparent areas stay transparent.
WebP already offers better compression efficiency than JPG or PNG at equivalent visual quality, so if your target platform supports it, compressing within WebP usually beats converting away from it and then compressing again.
For static WebP images, yes — enter a target size in MB and the tool adjusts quality automatically to get as close as possible. Note this tool works on static WebP images, not animated WebP sequences.
No — all compression happens locally in your browser using the Canvas API. Your files stay on your device throughout, so the process is private and works offline once the page has loaded.
