How to Sign a PDF on Your Phone
Last updated
Printing a PDF just to sign it and scan it back is an anachronism. Most jurisdictions accept electronic signatures for ordinary business contracts, and your phone is more than capable of producing one in seconds.
This guide covers signing a PDF on iPhone or Android using the PDF Editor app. The signature you save is reusable for every future document — you only have to draw it once.
Step by step
- 1
Open the PDF
Import via Files, your email, or any sharing app.
- 2
Tap the Sign tool
Found in the editing toolbar. Pick handwritten signature, typed signature, or initials.
- 3
Draw or type your signature
First time only. Use your finger or a stylus. Save it so you don't have to repeat the step.
- 4
Place the signature
Drag it to the right spot. Resize with corner handles. Add a date stamp if needed.
- 5
Export the signed copy
Save as a new file (keep the original unsigned) or overwrite. Share via email or any app.
Tips
- A stylus produces a much cleaner signature than a fingertip — worth it for contracts that go through visual review.
- Saved signatures live on your device, never on a server.
- Use a typed signature for routine acknowledgments, a handwritten one for contracts.
