Normal Sign & Digital Signature in PDF

A PDF document allows for two types of signatures: a normal sign and a digital signature.

A normal sign represents handwritten signatures or initials.

While a digital signature offers more security by verifying the signer’s identity. It ensures the document’s integrity.

Why Users Can’t Add Signature to PDF

There are several reasons that can hinder users from adding a signature:

• The PDF might be secured or protected.
• Permission restrictions.
• Faulty or outdated software.
• Document settings not permit signatures.

Signing Not Allowed in PDF? Here Are the Solutions

There are primarily two ways to resolve the “can’t add signature to pdf” issue. The first method is to use Adobe Acrobat Pro DC or other PDF editors to remove PDF restrictions. This method requires users to have the permission password for removal. The second method is to use professional software that does not require any password to remove such restrictions. If users are still unable to add signature to PDF in Adobe, then they can try updating the software or check the PDF file for corruption.

Method 1 – Adobe Acrobat Pro DC

Adobe Acrobat Pro DC is the premium version of Adobe Acrobat Reader. It provides advanced tools and features that include the ability to add signatures to PDF files even when signing is not allowed in PDF. Of course, the user needs to remove such settings first from the document to enable signing in PDF. Here is the process to do so:

1. Open the PDF with Adobe Acrobat Pro DC.
2. Go to ‘File’ > ‘Properties’.
3. Under the ‘Security’ tab, check the document restrictions. If “Signing” is not allowed, you need to change the settings.
4. Select ‘No Security’ from the dropdown.
5. Since the permissions are password protected, enter the password.
6. Save the changes with ‘Ctrl+S’ and try signing again.

This way even if users can’t add signature to PDF file in Adobe in the beginning, they can remove the settings and sign in without any problems. However, if the user does not have the permission password, then opt for the second method.
