How to Fix PDF Comments and Pop-Up Notes Not Opening for Recipients
Question details
A sender adds comments and pop-up notes to a PDF, but the recipient cannot open or read the text inside the notes despite seeing the comment indicators.
- Product
- Device & OS
- not provided
- Scenario
- Sharing an annotated PDF document with colleagues, clients, or external reviewers for feedback.
- Observed behavior
- The recipient can see comment indicators (like icons or highlights) on the document, but clicking or hovering over them fails to open the pop-up notes or display the comment text.
Verify that the PDF file itself is not corrupted by opening it on your own device first to ensure the comments and pop-up notes function correctly before troubleshooting the recipient's software.
Verify and Change the Recipient's PDF Viewer
Many built-in OS viewers or web browsers do not fully support interactive PDF annotations. Changing the recipient's default viewer usually resolves this issue.
The most common reason for inaccessible PDF comments is that the recipient is opening the document in a web browser or a basic system preview tool, rather than a dedicated PDF reader. Even if they have a standard PDF application installed, their computer might still default to opening PDFs in a browser.
Ask the recipient which application they are actively using to view the file. Do not just ask if they have a PDF reader installed, as the file may still be opening in a different default program.
Ask the recipient to send a screenshot of the visible comment indicator. This helps diagnose whether they are experiencing a rendering issue or using an incompatible viewer.
Recommend that the recipient opens the file using a fully compatible PDF viewer. Instruct them to right-click the PDF file, select 'Open with' from the context menu, and choose the dedicated PDF software instead of their web browser.

Frequently Asked Questions
Why do PDF comments show up as blank boxes?
Blank boxes typically occur when the PDF viewer lacks support for the specific annotation format used, or if the recipient's system is missing the fonts required to render the comment text properly.
Can I print the PDF with the pop-up comments visible?
Yes. In standard PDF editors like WPS Office, you can go to the Print dialog and look for an option to print 'Document and markups' or specifically choose to 'Print pop-up notes' so they appear on the physical copy.
How do I ensure my comments are visible to everyone regardless of their software?
To guarantee visibility, you can 'flatten' the PDF before sending it. This merges the comments permanently into the document's base visual layer. Note that flattened comments will no longer be interactive, editable, or capable of being hidden.
Why do my PDF attachments open in a web browser by default?
Most modern operating systems set the default web browser (such as Edge or Chrome) as the default PDF handler for convenience. You can change this behavior by right-clicking a PDF file, selecting 'Properties' (Windows) or 'Get Info' (Mac), and changing the 'Opens with' application to your preferred dedicated PDF reader.
