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.
Can I place typed text or a date instead of an image?
Yes — use text mode to place a name, date, approval note, or check mark at the selected position.
