How to Fix Digital Signature Feature Grayed Out in Adobe Acrobat
Question details
The user is unable to use the digital signature feature in Adobe Acrobat because the signing option is grayed out and inaccessible for a specific document.
- Product
- Adobe Acrobat 10.1.12
- Device & OS
- not provided
- Scenario
- Attempting to digitally sign a specific PDF document.
- Observed behavior
- The digital signing feature is disabled and grayed out for the current document, despite functioning correctly on other PDF files.
Before troubleshooting, verify if you have the permissions password for the document, as you cannot bypass digital signature restrictions on a securely locked PDF without it.
Check and Remove PDF Security Restrictions
Identify if the PDF is restricted by checking for the 'SECURED' tag and remove the security settings to re-enable the digital signature feature.
When a PDF document is created, the author can apply security restrictions that prevent further modifications, including adding digital signatures. If the signing options are grayed out, it is highly likely the document is secured.
Look at the very top of the Adobe Acrobat application window. If you see the word '(SECURED)' appearing next to the file name, the document has active security restrictions.
Navigate to 'File' > 'Properties' from the top menu, then click on the 'Security' tab. Review the 'Document Restrictions Summary' to confirm that 'Signing' is listed as 'Not Allowed'.
To enable signing, click the 'Security Method' drop-down menu and select 'No Security'. If prompted, enter the permissions password provided by the document owner.
Click 'OK' to apply the changes, then save the document (File > Save). The digital signature options should now be fully active and accessible.
Add Digital Signatures to PDFs Quickly with WPS Office
Bypass complicated settings and easily digitally sign your PDF documents using WPS Office's built-in PDF editor. It provides a straightforward way to add, manage, and verify signatures seamlessly.
- 1. Open the PDF in WPS Office: Launch WPS Office, select the 'PDF' tab, and click 'Open' to load the document you need to digitally sign.
- 2. Navigate to the signature tools: On the top ribbon menu, click the 'Fill & Sign' or 'Protect' tab to access the built-in signature options.
- 3. Create your signature: Click the 'Sign' button and select 'Create Signature'. You can choose to type your name, draw your signature, or insert an image of your physical signature.
- 4. Apply and save: Place the signature anywhere on the PDF document by clicking on the desired location, then save the file to finalize your signature.
Frequently Asked Questions
Why does my PDF say SECURED in the title bar?
The 'SECURED' label indicates that the author of the PDF has applied password protection or permission restrictions. These restrictions limit user actions such as printing, editing, copying, or digitally signing the document.
Can I force a signature on a secured PDF without the password?
No, you cannot add a digital signature to a secured PDF unless you have the permissions password to remove the specific restrictions placed by the original author.
How do I remove security from a PDF if I am the owner?
Open the PDF, go to 'File' > 'Properties' > 'Security', and change the Security Method to 'No Security'. You will need to enter the permissions password you originally set to unlock all features, including signing.
Will the digital signature option gray out if my certificate is expired?
Yes. If the digital ID or certificate you are trying to use has expired or is invalid, the signing options or the specific signature profile may become disabled or grayed out until you import a valid certificate.
