Compress WebP Online — Free, Fast & Private

WebP is already an efficient format, but further compression can squeeze out additional savings. MiniPx re-encodes your WebP files at your chosen quality level, often reducing size by another 20-40% beyond what the original encoder achieved.

This is especially useful when you have WebP files exported at high quality (90%+) that could be optimized for web delivery at quality 78% without any perceptible difference.

How it works

  1. Upload WebP: Drag your WebP files into MiniPx
  2. Set quality: Choose Smart for balanced compression
  3. Compress: Click the compress button
  4. Download: Save optimized WebP files
