Does WEBP keep transparency?

Yes. Unlike JPG, WEBP supports a full alpha channel, so transparent PNGs stay transparent after conversion.

Is WEBP supported everywhere?

Every modern browser displays WEBP. A few older desktop apps still expect PNG, so keep the original if you need maximum compatibility.

Are my files uploaded to a server?

No. The whole conversion runs in your browser using your device's own processor. Your files are never sent anywhere.
