Question details
The user is unable to edit text comments because they are locked, and the option to unlock them in the properties menu is greyed out or unavailable.

- Product
- PDF Editor
- Device & OS
- not provided
- Scenario
- Attempting to modify, lock, or unlock text comments within a PDF document.
- Observed behavior
- Text comments cannot be edited, and the lock option is completely greyed out. This issue may occur in a single document or across all PDFs opened by the user.
Verify whether the entire PDF document is secured with a permissions password, which restricts commenting and editing features globally.
Check Document Security and Save a Copy
Resolve issues restricted to a single PDF by removing security restrictions or saving a fresh, uncorrupted copy.
If the issue only happens with one specific PDF, the file may have restricted editing permissions or minor file corruption preventing property changes.
Open the affected PDF document and check the document properties (usually under File > Properties > Security) to see if commenting and editing are allowed.
If the document is secured, enter the required permissions password to unlock the editing features.
If there is no password restriction but the lock option remains unavailable, go to File > Save As and save a new copy of the document to a different local folder.
Open the newly saved copy and attempt to edit or unlock the comment again.

Frequently Asked Questions
Why can't I edit text comments in my PDF?
Text comments may be locked, or the document itself might have a security password restricting modifications. Check the document's security properties to ensure commenting is permitted.
What is the difference between a text comment and a text box in PDFs?
A standard text comment is generally a simple text markup that may not support advanced locking properties in all PDF viewers. A text box is an adjustable graphic element that contains text and fully supports locking and formatting properties.
How do I unlock a locked comment in a PDF?
Right-click the locked comment, select Properties, and uncheck the 'Locked' box at the bottom of the properties window. If this option is greyed out, verify that you have permission to edit the document.
