How to use Sign PDF
- 01
Choose your PDF and the page to sign.
- 02
Draw, type or upload your signature, then choose its position.
- 03
Save your signed copy and keep the original.
Place a visible mark on the right page
Choose the page, create your signature and use the preview to position it. A transparent PNG can be useful when uploading a signature image. Check the downloaded page before sharing it; the original PDF remains separate. The signature guide walks through sizing and placement.
Complete fields before signing
Use Fill PDF Forms for supported interactive form fields first. This signing tool adds a page mark and does not verify identity, create an audit trail or fill a certificate signature field. Follow the recipient’s requested signing method when they specify one.
