The user needs to import a scanned handwritten signature into Adobe Acrobat Reader DC to sign digital documents.

How to Import a Signature Image into Adobe Acrobat Reader

Product: Adobe Acrobat Reader DC
Device & OS: not provided
Scenario: Signing digital PDF documents with a scanned version of an actual, handwritten signature rather than a typed or mouse-drawn one.
Observed behavior: Following a recent software update, the user is unable to directly import their scanned signature from a saved PDF or Word document into Adobe Reader.

Before you start

Before attempting to import your signature, ensure that your scanned handwritten signature is saved as a standalone standard image format, such as PNG or JPG, rather than embedded inside a Word or PDF document.

Solution 1Recommended

Convert and Import the Signature as an Image File

Extract your scanned signature from the Word or PDF document and save it as a supported image file (PNG/JPG) to successfully import it into Adobe Acrobat Reader.

Adobe Acrobat Reader's 'Fill & Sign' feature strictly requires signature files to be in common image formats. It cannot directly read an image that is embedded within a .docx or .pdf file.

Save the signature as an image

Open the Word or PDF document containing your scanned signature. Take a screenshot of just the signature, or right-click the image (in Word) and select 'Save as Picture' to save it as a PNG or JPG file to your computer.

Open Fill & Sign

Launch Adobe Acrobat Reader DC and open the PDF document you want to sign. Click on the 'Fill & Sign' tool located in the right-hand tool pane.

Add a new signature

Click the 'Sign yourself' icon at the top toolbar, then select 'Add Signature' from the dropdown menu. If you already have a saved signature, you may need to click the minus (-) icon next to it to clear it first.

Select the Image option

In the signature panel, click the 'Image' icon or text option. Browse your computer for the PNG or JPG file you saved in step 1, select it, and click 'Apply'.

Convert and Import the Signature as an Image File

Signature Security: Keep your saved signature image file in a secure location on your device. Never share your standalone signature file publicly to prevent unauthorized use.

Solution 2

Use Adobe Acrobat Web Fill & Sign Tool

If the desktop application continues to encounter errors after a recent update, utilizing the web version can help you bypass local software glitches.

Frequently Asked Questions

Why can't I import my signature directly from a Word document?

PDF readers like Adobe Acrobat require signature files to be standalone image formats (such as JPG, PNG, or BMP). They cannot extract image data embedded inside word processing documents (.docx) or other PDF files during the signature creation process.

How do I create a signature image with a transparent background?

To get a transparent signature, sign your name on a blank white piece of paper with dark ink. Scan it or take a clear photo, then use a free online background remover or image editing software to erase the white background. Save the resulting file in the PNG format, which supports transparency.

What should I do if the 'Add Signature' option is missing or greyed out?

This usually indicates that the PDF document is encrypted or has restricted permissions set by the creator. Go to File > Properties > Security to check if signing is permitted. If it is restricted, you will need the document password or must request the author to provide an unrestricted copy.
