About this tool
WebP is Google's modern image format. It produces files that are typically 25–35% smaller than JPEG at the same perceived quality, and unlike JPEG it also supports transparency and animation. Every major browser now supports WebP, which is why it's increasingly the default for performance-conscious websites.
This WebP Compressor lets you re-encode WebP images to a smaller size, either by picking a quality level or by targeting a specific file size in KB. Everything runs locally in your browser — your image is never uploaded to a server.
If you have a JPEG or PNG and want the savings without changing your workflow, our converter tools let you switch formats first, then compress.

Tips for best results
WebP at 75 looks roughly like JPEG at 85. You can usually drop the quality value 5–10 points compared to your JPEG defaults.
Modern browsers all support WebP, but if you serve legacy Internet Explorer users, keep a JPEG fallback.
Frequently asked questions
Does WebP support transparency?
Yes. The compressor preserves alpha channels in the output.
What's a good WebP quality?
75–85% is usually visually lossless for photos and far smaller than JPG at the same quality.
