FAQ

Are my files uploaded to a server?

No — everything runs locally in your browser; your files never leave your device.

Can the stamp image have a transparent background?

Yes — a PNG image's transparency is preserved, so a signature or stamp with a transparent background overlays cleanly onto the page.
