You can use multiple annotation types in one session, such as highlighting text and adding sticky notes for detailed feedback.
This runs in the Acrobat app - there is no separate API for this task.
Comments are usually text-based notes like sticky notes or text boxes, used for written feedback. Drawing markups, however, are visual elements like lines, circles, or highlights that you draw directly on the document. Both help you review, but comments explain with words, while drawing markups point out things visually. You might use a highlight (markup) to show an important sentence, then add a sticky note (comment) next to it to explain why it's important.
Sanitizing your PDF is very important because comments and markups are stored as a separate layer. If you share a 'final' document without sanitizing it, others can still see all your review notes and private comments. Sanitizing removes this hidden data, making sure that sensitive information or internal discussions do not accidentally leak when you send the file outside your team. It protects your privacy and the document's final appearance.
When many people review a document, Acrobat helps you manage all the feedback. You can usually see a list of all comments in a 'Comments List' panel. This panel lets you sort comments by author, date, or type. You can click on a comment in the list to jump directly to it in the document. This makes it simple to track and respond to all the different suggestions from your team.
