Questions

Is this a legal digital signature?

It places an image of your signature on the PDF, like signing a printed page. It is not a certified digital signature (with a certificate). Check what your office or authority accepts.

Can I put the stamp on every page?

Yes. Tick "Same place on all pages" in the Stamp tab.

Where is my signature saved?

Only in this browser on your device, so you do not have to draw it again. It is never uploaded.
