Scenario
Attempting to annotate a PDF document using the comment cloud tool for reviewing or highlighting specific areas.

Before you start

Before troubleshooting the software, ensure you have the necessary permissions if the PDF was sent by someone else, as restricted documents often disable specific commenting tools.

Solution 1Recommended

Check PDF Security Permissions

Verify if the specific PDF document has security restrictions that prevent adding annotations and comments.

PDF creators often apply security settings to prevent unauthorized editing, copying, or commenting. If the comment tools are grayed out, the document is likely restricted.

1
Open Document Properties

Open the problematic PDF in Adobe Acrobat, right-click anywhere on the document page, and select 'Document Properties' from the context menu.

2
Navigate to the Security Tab

In the Document Properties dialog box, click on the 'Security' tab at the top.

3
Check Restrictions Summary

Review the 'Document Restrictions Summary' list. Look for the 'Commenting' row and verify whether its status is listed as 'Allowed' or 'Not Allowed'.

Check PDF Security Permissions
Password Requirement: If commenting is set to 'Not Allowed', you will need to request an unprotected copy or obtain the permissions password from the document's author to unlock the annotation features.

Frequently Asked Questions

Why are all my commenting tools grayed out in a PDF?

This usually happens when the document is protected by a permissions password, or if you are viewing a PDF/A (archive) file which strictly restricts modifications to preserve the document's original state.

Can I add a comment cloud without Adobe Acrobat?

Yes, you can use alternative PDF editors like WPS Office, which feature built-in annotation tools allowing you to draw shapes, highlight text, and insert comment clouds easily and for free.

How do I remove security from a PDF to enable commenting?

If you have the permissions password, open the PDF, go to Document Properties > Security, and change the Security Method to 'No Security'. Enter the password when prompted, confirm the changes, and save the file.
