- Product
- PDF Editor
- Device & OS
- not provided
- Scenario
- Attempting to edit text or fill out forms in a PDF document that was previously saved.
- Observed behavior
- The PDF becomes locked, preventing further editing or the use of the Fill & Sign feature.
Verify that your PDF editing software is updated to the latest version, and ensure you are the original author of the document before attempting to bypass security restrictions.
Check for Digital Signatures and Clear Them
A digitally signed PDF is locked against further changes to protect its integrity. Signing should always be the final step when working with a PDF.
When a digital signature is applied to a PDF, the document is sealed. Any subsequent changes to the text or form fields are restricted to prevent tampering and ensure the signature remains valid. If you are the original signer, you may be able to clear your signature to regain editing rights.
Open your PDF file and look for a banner at the top or a signature panel on the side indicating that the document has been signed.
Right-click on the digital signature field within the document and select 'Clear Signature'. You must be the person who originally signed the document and have the corresponding digital ID on your device.
Once the signature is cleared, save the document (File > Save) and try using the Fill & Sign or Edit tools again.
Check Document Permissions and Security Restrictions
The PDF might have been saved with a permission password that restricts filling, signing, or editing.
Request an Unsigned or Original Copy
If the document was signed by someone else or you do not have the permissions password, you will need the original file.

Frequently Asked Questions
Why does my PDF lock completely after I sign it?
Digital signatures are specifically designed to verify a document's authenticity and integrity. Once a signature is applied, PDF software locks the file to prevent unauthorized modifications that would invalidate the signature and compromise the document's legal standing.
Can I edit a PDF that has been digitally signed by someone else?
Generally, no. Editing a signed PDF invalidates the existing signature. If you need to make changes or add information to a document signed by another party, you must request an unsigned copy from them, make your additions, and then have all parties sign the new version.
How do I unlock a saved PDF if the Fill & Sign tools are grayed out?
If the tools are grayed out, the PDF is either signed or restricted by a permissions password. Go to File > Properties > Security to check for restrictions. If it is password-protected, change the Security Method to 'No Security' and enter the password. If it is signed, the signature must be cleared by the original author.
