- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Setting up a document review process where multiple participants can add comments to a shared PDF file.
- Observed behavior
- The goal is to distribute the file, collect annotations from reviewers, and maintain a controlled history of comments.
Ensure you have an active Adobe Acrobat subscription or a compatible PDF editor, and verify that all intended reviewers have internet access to sync their annotations.
Use the Send for Comments Feature in Adobe Acrobat
The standard and most efficient method for distributing a PDF to multiple reviewers to gather feedback and annotations in a controlled cloud workflow.
By using the native cloud-based review tools in Acrobat, comments are automatically synchronized. Reviewers only need a browser or the free Acrobat Reader to participate.
Launch Adobe Acrobat and open the PDF document you wish to share for review.
Click the 'Share' button located in the top right corner of the application window, or navigate to 'Tools' and select 'Send for Comments'.
Enter the email addresses of the participants you want to collaborate with. You can add a customized message outlining the review instructions.
Ensure the 'Allow comments' toggle is switched on so participants can add their annotations.
Click 'Send'. Participants will receive an email link allowing them to open the PDF and add sticky notes, highlights, and text comments.

Set Up an Internal Network Shared Review
Best for internal corporate teams where files must remain on a local network drive or internal server rather than the cloud.

Frequently Asked Questions
Can reviewers add comments to a shared Acrobat PDF without a paid subscription?
Yes, participants do not need a paid Acrobat Pro subscription. They can use the free Adobe Acrobat Reader or simply their web browser to view the document and add comments to a shared review PDF.
How do I prevent reviewers from deleting existing annotations made by others?
When using the 'Send for Comment' feature, the file author retains control. Participants can add their own comments and reply to threads, but they generally cannot delete or modify comments authored by someone else.
What happens if two people annotate the PDF at the exact same time?
In Adobe's cloud-based workflow, annotations are synchronized automatically as they are made. If using a local network folder review, Acrobat merges incoming comments seamlessly when the document connects to the network.
Is there a free alternative for annotating and sharing PDF documents?
Yes, WPS Office features a free, built-in PDF tool that allows you to read, annotate, highlight, and easily share PDF documents without requiring a premium software subscription.
