Frequently Asked Questions

Will disabling the comments pane delete the comments from my PDF?

No, changing this preference only hides the comments window from popping up automatically. All comments and annotations remain safely stored in the document.

How do I manually view comments after disabling the automatic pane?

You can manually open the comments pane at any time by clicking the Comment icon on the right-hand toolbar or navigating to the View or Comment tab in your PDF reader.

Can I hide comments permanently when printing a PDF?

Yes, when printing a PDF, you can usually choose to print 'Document' instead of 'Document and Markups' in the print dialog box to ensure comments are not printed on the page.

Why do comments open automatically by default?

PDF applications often enable this setting by default so that users do not miss important feedback, annotations, or review notes left by others in collaborative documents.
