- You can add comments to a PDF using any of the commenting and markup tools in Acrobat. Open the Comment pane to see all the tools available in the Annotations and Drawing Markups panels. To use a tool, select it, click on the page, and then select the text you want to edit, or draw your markup.
- Open the original PDF file that you sent out for review, and then choose Import Data File from the Comments List panel menu. Select the PDF or FDF files that reviewers returned to you, and click Select. Acrobat imports all the comments into the original document.
In an email-based review process, each reviewer receives the PDF document through email, makes comments, and returns the PDF document through email; reviewers do not see each others’ comments.
In a shared review process, you post the PDF document to a central server or folder, and then invite reviewers to make their comments. When reviewers publish comments, they can be seen by all other reviewers, so everyone can respond to each other. You can also enforce a deadline more easily with a shared review process, as commenting tools are no longer available to reviewers after the deadline.
