How to sign a PDF on iPhone

Open a PDF, add your real handwritten signature, resize it, and share the signed copy from your iPhone.

Quick answer

In PDF Sign & Scan, import the PDF, tap Sign, choose or create a signature, place it on the page, then tap Send to share the finished PDF.

Step by step

    Bring in the PDF

    Open PDF Sign & Scan and choose a PDF from Files. You can also scan a paper document or import an image.

  2. 02

    Tap Sign

    Choose a signature you saved earlier. If this is your first time, scan one from paper or draw it on screen.

  3. 03

    Place it precisely

    Drag the signature to the line. Pinch to make it smaller or larger. Check the correct page before finishing.

  4. 04

    Share the signed copy

    Tap Send. The app creates a flattened PDF and opens the iOS share sheet so you can save or send it.

App Store

When Apple Markup is enough — and when it is not

  • Markup works well for a quick one-off signature drawn with your finger.
  • Use PDF Sign & Scan when you want the handwriting from paper, a reusable signature library, or more deliberate placement across PDF pages.
  • Keep the original PDF until you have checked the signed export.

Questions

Can I sign a PDF from the Files app?

Yes. Choose the PDF from Files inside the app, or use the iOS share sheet to send it to PDF Sign & Scan.

Can I resize the signature?

Yes. Drag to move it and pinch to resize it before exporting the PDF.
