Like every free tool by Digital Heroes, PDF Sign has no usage limits.

Add a date or text stamp alongside your signature, with adjustable font size.

Place and reposition the signature box on any page by clicking, dragging, or entering exact coordinates.

Download a signed PDF with the signature and text baked in, with no quality loss.
