Does WebP keep transparency?

Yes — WebP supports an alpha channel, so transparent PNGs stay transparent and are typically much smaller.

Are my files uploaded to your servers?

No. The conversion runs entirely inside your browser using your own device. Your files never leave your computer, so the tool is private and works even for confidential documents.
