Open your PDF file in Adobe Acrobat.
Click the Comment button in the toolbar to display the commenting tools.
Select the annotation tool you want to use, such as Note, Highlight, Text Box, or Draw.
Click on the PDF page where you want to add your comment or annotation.
Type your comment or draw your annotation as needed.
Click away from the annotation or press Escape to save your comment or annotation.
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.
Highlighting text simply marks specific words or sentences with a color, making them stand out. It's good for drawing attention to existing content. Adding a text box comment, however, lets you write new text directly onto the page in a visible box. This is useful for adding longer explanations or new information that isn't part of the original document. Both are types of annotations, but they serve different purposes for reviewing content.
It is very important to flatten or sanitize your PDF because comments and markups are stored as a separate layer of data. If you just save the file, anyone who opens it can still see or recover your review notes, even if they don't appear on the surface. This can lead to private information or internal review thoughts being shared by mistake. Sanitizing removes all hidden data, ensuring only the final, clean document is sent, protecting your privacy and preventing information leaks.
If your document has many comments, Adobe Acrobat usually provides a 'Comments List' or 'Comments Pane'. You can find this by clicking on the 'Comment' tool. This pane shows all comments in a list, often grouped by page or type. You can click on each comment in the list to jump directly to its location in the document. This makes it easy to read and respond to all feedback without searching through every page.
