How to use Sign PDF
Place a visual signature on one or more pages. Type your name, draw with touch or a pointer, or choose a signature image. This is not a certificate-backed digital signature and does not verify identity or detect later changes.
- Choose an unlocked PDF, then choose a page.
- Create your signature and tap the preview to place it. Adjust its size and position.
- Add it to the page, repeat if needed, and save a signed copy.
A practical example
Add a drawn signature on the last page and initials on another page.
Before you share the result
