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

Review every placement before sharing. Keep the original document.
Signatures become flattened page content, not cryptographic signatures or identity checks.
Interactive editing supports up to 200 pages and 20 MB; password-protected files must be unlocked first.
