How to sign a scanned PDF on iPhone

Add a saved handwritten signature on top of a scanned PDF page without converting the scan to editable text.

Quick answer

Import the scanned PDF—or scan the paper document in the app—then place your saved signature on the page. OCR is not required because the signature is placed over the scan.

Step by step

  1. 01

    Import or scan the document

    Choose the existing PDF from Files, or use Scan Document to capture the paper pages. Check page edges and order before signing.

  2. 02

    Choose a saved signature

    Tap Sign and select the correct handwritten signature from your on-device library.

  3. 03

    Place it over the scan

    Drag the signature to the intended line and pinch to resize it. A scanned page does not need an editable form field for this placement.

  4. 04

    Export and inspect

    Create the flattened signed PDF, open the exported copy, and make sure the signature is readable at normal page size.

What this does—and does not do

  • The signature is placed visibly on the scanned page.
  • The app does not run OCR or turn the document text into editable fields.
  • If the recipient requires a certified digital signature, use their specified workflow.

Questions

Can I sign a PDF that is just scanned images?

Yes. The saved signature is placed on top of the page image.

Do I need OCR first?

No, not for visible signature placement. OCR is only relevant when you need selectable or editable text.
