Compress WebP — Reduce WebP File Size in Your Browser

This WebP compressor reduces WebP file size by re-encoding at a lower quality, fully in your browser. WebP is already smaller than JPG at the same quality; this tool lets you push file size down even further when bandwidth or storage is tight.

WebP is the modern web image format, supported by every major browser. A typical WebP is 25–35% smaller than the JPG it replaced, but those savings can still leave room when the goal is fast page loads, small chat uploads, or efficient asset bundles. Lowering quality even slightly often produces a noticeably smaller file with no visible difference.

Drop in one or more WebP files, pick a target quality, and the tool re-encodes locally in your browser. Optionally cap the longest edge to downscale large images. The result panel shows the original vs. compressed size and percentage saved.

Transparency is preserved through the compression pass. Multi-file batches return as a ZIP. Because everything runs locally, you can compress private images without uploading them to a third-party tool.
