How to sign a document on your iPhone
You don't need to print a form, sign it, and scan it back. Printer App lets you draw a signature once, drop it onto any PDF or scan, and export a signed copy — all on your phone.
Sign a document
- Open the PDF or scan in Printer App.
- Choose Sign and draw your signature with your finger (or save one to reuse).
- Drag the signature to the right spot and resize it to fit the line.
- Add the date or any text fields you need.
- Export or share the signed PDF, or print it.
FAQ
- Is a drawn signature legally valid?
- For most everyday agreements a drawn signature is widely accepted, but requirements vary by document and jurisdiction. For anything important, check what the other party or the law requires.
- Can I reuse the same signature?
- Yes. Save your signature once and place it on future documents without redrawing it.
