Q: Are images uploaded to the server?

No. All processing happens in your browser. Images never leave your device.

Q: What about transparent backgrounds after PNG to JPEG?

JPEG does not support transparency. A white background is filled in automatically during conversion.

Q: How compatible is WebP?

Modern browsers generally support WebP. For use on older devices, we recommend converting to JPEG or PNG.
