Solution 1Recommended

Verify PDF Security Settings and Permissions

The PDF document itself may have specific security restrictions applied by the author that prevent any commenting or editing capabilities.

Even with an active Acrobat Pro subscription, you cannot comment on a file if the original creator has locked it down with a permissions password.

1
Open the PDF File

Launch Adobe Acrobat or your default PDF reader and open the problematic PDF document.

2
Access Document Properties

Click on 'File' in the top left corner of the menu bar, then select 'Properties' from the dropdown list.

3
Check the Security Tab

Navigate to the 'Security' tab within the Document Properties window.

4
Review Commenting Allowances

Look under the 'Document Restrictions Summary' and check if 'Commenting' is marked as 'Allowed' or 'Not Allowed'. If it is not allowed, you will need the permissions password to unlock the file.

Password Requirement: If the file is restricted, you must contact the original document owner to obtain the permissions password to enable commenting.

Frequently Asked Questions

Why does my PDF say commenting is not allowed?

The author or creator of the PDF document has applied security restrictions. You can confirm this by going to File > Properties > Security and viewing the Document Restrictions Summary to see if commenting is blocked.

Does my Creative Cloud subscription include Acrobat Pro?

It depends on your specific subscription plan. The 'All Apps' plan includes Acrobat Pro, but 'Single App' or 'Photography' plans generally do not, which is why you may be prompted to upgrade when using premium PDF features online.

Can I comment on a PDF online for free without Adobe?

Yes, many alternative desktop software options and online tools, such as WPS PDF, allow you to add basic comments, highlights, and annotations to standard, unrestricted PDF files without requiring a premium subscription.
