Question details
Users experience inactive or unclickable hyperlinks in a PDF document immediately after applying a digital signature.
- Product
- Device & OS
- not provided
- Scenario
- Applying a digital signature or certifying a PDF document that contains interactive hyperlinks.
- Observed behavior
- The hyperlinks work normally before signing, but become inactive, unclickable, or entirely broken once the digital signature is applied to the PDF.
Ensure you have a backup copy of the original, unsigned PDF file, as removing a digital signature or altering certification settings may invalidate existing document approvals.
Adjust Signature Certification and Permission Settings
Modifying the permissions when certifying the document ensures that interactive elements like hyperlinks remain active after the document is signed.
When a PDF is digitally signed, the author can choose to completely lock the document to prevent tampering. If a document is locked without exceptions, interactive elements like hyperlinks may be automatically disabled by the PDF viewer to ensure security. By allowing specific permitted changes during the signing process, you can keep links functional.
Open the original, unsigned PDF document in your preferred PDF editor.
Navigate to the digital signature or certification tool and select the option to sign or certify the document.
Look for a 'Permitted changes after certifying' dropdown menu or a similar permissions setting in the signature dialog box.
Select an option that allows for annotations, form fill-in, or general interactions rather than choosing 'No changes allowed'.
Apply the signature, save the document as a new file, and click the hyperlinks to verify they are now active.
Test the Signed PDF in a Dedicated Desktop PDF Reader
Verify if the issue is caused by the viewing software rather than the document itself, as some browsers disable links in signed PDFs.

Frequently Asked Questions
Can I edit a PDF hyperlink after the document has been digitally signed?
Generally, modifying a hyperlink in a digitally signed PDF will invalidate the signature. To edit a link, you must clear the existing signature, make your hyperlink adjustments, and then resign the document.
Why do hyperlinks work before signing but not after?
Applying a signature often locks the document to prevent unauthorized modifications. If the security settings applied during the signing process are set to 'No changes allowed', many PDF viewers will disable interactive elements, including hyperlinks, to ensure complete document integrity.
How do I remove a digital signature to fix my broken links?
If you are the original author or possess the digital ID used to sign, you can usually right-click the signature field and select 'Clear Signature'. Once cleared, the document unlocks, allowing you to fix the hyperlink properties before applying the signature again.
