Does the conversion lose quality?

WebP is a lossy format, but at the default quality the difference from the original is invisible to the eye. Lower the quality only when you need the smallest possible file.

What happens to transparency?

WebP supports transparency, so transparent areas in the source are preserved.

Can I convert many files at once?

Yes, add up to 100 files and they are converted one after another in your browser. The results can be downloaded together as a ZIP.

Are my files uploaded to a server?

No. This tool runs entirely inside your browser using JavaScript. Your files are read from your device, processed in memory, and the result is handed straight back to you as a download. Nothing is transmitted, stored or logged, and the page keeps working if you go offline after it has loaded.
