Frequently Asked Questions

Why are my PDF comments loading slowly on my mobile device?

Slow loading times for comments are typically caused by outdated application versions, low device memory, or extremely large PDF files containing excessive graphics. Updating your app to the latest version and closing background apps usually resolves the issue.

Can I view comments made on my mobile device when I open the PDF on a computer?

Yes. Standard PDF comments, highlights, and sticky notes added in mobile apps like Adobe Acrobat or WPS Office are embedded within the file structure. They are fully compatible and visible when the file is opened on any desktop PDF reader.

How do I edit or delete an existing comment on a mobile PDF reader?

Simply tap on the highlighted text or the sticky note icon within the document. A context menu will pop up, allowing you to edit the text of your note, change its color, or delete the comment entirely.
