How to Restrict SharePoint Reviewers to See Only Their Own PDF Comments
Question details
The user needs to set up a shared PDF review on SharePoint where multiple reviewers can only see their own markups, while the document owner can access and consolidate all comments.

- Product
- SharePoint / PDF
- Device & OS
- not provided
- Scenario
- Managing a collaborative PDF review process with multiple stakeholders where feedback must remain isolated and confidential between each reviewer and the owner.
- Observed behavior
- SharePoint and standard PDF readers do not support an isolated shared-review workflow, causing all reviewers to see each other's comments and markups by default.
Ensure you have the original master PDF file saved locally and that your chosen PDF software supports exporting and importing FDF (Forms Data Format) files for comment management.
Distribute Local Copies and Merge FDF Comment Files
Since SharePoint does not support isolated comment viewing in a shared environment, the best approach is to send individual copies to reviewers and consolidate their feedback offline.
Currently, neither SharePoint nor standard PDF applications provide a native feature to hide other reviewers' comments while keeping them visible to the owner in a single shared file. To achieve isolated reviews, you must transition from a centralized SharePoint link to a decentralized local file workflow.
Instead of sharing a single SharePoint document link, download the PDF and email a separate local copy directly to each of the reviewers.
Instruct your reviewers to open their local copy, add their comments, and then export those comments as an FDF (Forms Data Format) file using their PDF reader's comment management tools. They should then email only the FDF file back to you.
Open your master PDF file locally. Use the 'Import Data' or 'Import Comments' feature in your PDF software to load each of the FDF files you received. This will overlay all individual comments onto your master document for easy consolidation.

Frequently Asked Questions
Can I hide other reviewers' comments directly in SharePoint?
No, SharePoint shared reviews do not currently support permission-based visibility for individual comments. If a PDF is shared centrally, anyone with access to the document can see all embedded comments.
What is an FDF file?
FDF (Forms Data Format) is a lightweight file format used specifically for exporting and importing data from PDF documents. It allows you to share comments and form data without needing to send the entire original PDF file.
Is there a way to password-protect individual PDF comments?
While you can restrict editing, copying, or printing of a whole PDF using a permissions password, standard PDF formats do not allow you to password-protect or isolate individual comments for specific users.
