Fix Digital Signing Disabled After Enabling PDF Form Filling
Question details
Users are unable to apply digital signatures to a PDF after extending the document's permissions to allow form filling and saving in standard PDF readers.
- Product
- Device & OS
- not provided
- Scenario
- Extending a PDF form's permissions so standard reader users can fill and save it.
- Observed behavior
- The digital signing feature becomes restricted or entirely disabled once the form filling extension is applied and the file is saved.
Ensure you have access to the original, unprotected master copy of your PDF file before modifying its extension properties or security settings.
Adjust Reader Extension Settings to Preserve Signatures
Select the correct Reader Extension configuration when saving your PDF to ensure users can both fill forms and apply digital signatures.
When you extend a PDF for users with standard reader software, applying the wrong extension type can lock down the document and prevent signing. You must explicitly allow users to change and save forms.
Launch Acrobat Standard or Pro and open your original, unrestricted PDF form.
Navigate to the 'File' menu, select 'Save as Other', and then choose 'Reader Extended PDF'.
Select the option specifically labeled 'Enable More Tools (includes form fill-in & save)' or 'Enable users to change and save forms'. This ensures the signature functionality is preserved alongside form editing.
Save the new copy of your document. Press Ctrl+D to open Document Properties, go to the Security tab, and verify that 'Signing' remains 'Allowed'.
Remove Restrictive Security Policies
Check if an underlying password security policy is overriding your form extensions and blocking signatures.

Frequently Asked Questions
Why does enabling form filling disable digital signatures in my PDF?
This occurs because applying basic reader extensions often restricts other advanced modifications to protect document integrity. If you do not specifically choose the extension setting that preserves signature rights, the software locks the signing capability.
Can I remove reader extensions to restore digital signing functionality?
Yes. If you open the extended PDF in a professional PDF editor and choose to 'Save a Copy', it typically strips away the reader extensions and restores the document's original, unrestricted permissions, allowing you to sign it.
Does WPS PDF require special settings to allow form saving and signing?
No. In WPS PDF, as long as the document isn't explicitly password-protected against editing, users can naturally fill out interactive fields, add their signature, and save the file without needing to configure complex 'Extended' configurations.
