Compress WebP Online Online

Reduce WebP file size instantly with our free online WebP compressor. Upload your WebP image, adjust the quality level, and download a smaller optimized file — all inside your browser without installing any software.

Every image is processed locally using the HTML5 Canvas API. Your WebP files are never sent to a server, keeping your images completely private.

WebP is already one of the most efficient image formats, but further compression can significantly reduce file sizes for web performance optimization.

WebP already offers superior compression compared to JPG and PNG, but large or high-quality WebP files can still be reduced further.

Compressing your WebP images helps you:

• Achieve even smaller file sizes for faster pages
• Reduce bandwidth usage and hosting costs
• Improve Lighthouse performance scores
• Meet strict upload size requirements
• Optimize images for mobile connections
• Boost SEO through faster page load times

WebP supports both lossy and lossless compression. This tool uses lossy re-encoding via Canvas, which typically delivers the best file size reductions while keeping quality high.
