What is WebP compression?

WebP compression re-encodes your image at a lower quality setting, trading a small, often invisible amount of visual detail for a meaningfully smaller file size, while keeping the same WebP format. WebP is a modern image format developed by Google that supports both lossy and lossless compression, transparency, and animation — typically producing smaller files than JPG or PNG at comparable quality.

How to compress a WebP file

Choose a WebP file using the drop zone above (or drag and drop it in).
Adjust the compression level if you like, then click "Compress".
Click "Download" to save your smaller WebP file.

Why compress a WebP file?

A smaller WebP file uploads faster, loads faster on a website, and takes up less storage or email attachment space — often with no visible difference in quality.

Is this private?

Yes. This WebP compressor runs entirely in your browser using the Canvas API — your file is never uploaded to our servers, stored, or logged. Closing this tab discards everything.

Supported browsers
