About WebP Compressor

WebP Compressor re-encodes your WebP images at a lower quality setting to shrink file size. WebP is Google's modern image format, already smaller than an equivalent JPG or PNG at the same visual quality — this tool compresses it further using the same lossy trade-off as JPG, controlled by the quality slider. This is a lossy re-encode, not WebP's separate lossless mode, so expect the same small, usually invisible trade-off you'd get compressing a JPG. It's great for cutting page weight on WebP images that were exported at a higher quality than a page actually needs. Everything happens locally in your browser, so your files are never uploaded anywhere.

How to compress a WebP

  1. 1

    Add your WebP files

    Drag and drop your WebP images, or click to browse. You can add several at once.

  2. 2

    Pick a quality

    Use the slider or a quick preset — lower quality means a smaller file. It recompresses automatically as you adjust it.

  3. 3

    Download

    Save each file individually, or download every compressed file at once as a .zip.

FAQ

Will compressing my WebP lose quality?
Yes, a little — this tool re-encodes WebP using the same lossy trade-off as JPG, not WebP's separate lossless mode. At the default 80% quality the difference is rarely visible.
Isn't WebP already compressed?
Yes, but WebP supports a wide quality range just like JPG. If your source was exported at a higher quality than you need, re-compressing it here can still shrink it noticeably.
Are my files uploaded anywhere?
No. Compression runs entirely in your browser — your files never leave your device.
Is there a file size limit?
Each file can be up to 25MB, and up to 20 files per batch, to keep things reliable on mobile browsers.
