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 is used to make text stand out by coloring it, like with a marker. It's best for pointing out specific words or sentences. Drawing markup lets you add shapes like circles, arrows, or lines. This is useful for pointing to areas on a page, images, or sections that do not have text, giving you more freedom to visually explain issues. Both are types of annotations, but they serve different visual purposes for feedback.
You should sanitize your PDF to protect privacy and prevent information leaks. When you add comments and markups, they are stored as a separate layer of data. If you share the file without sanitizing, others can see your review notes, even if they appear hidden. Sanitizing removes all comments, hidden data, and metadata, ensuring only the final, clean document is shared. This is important for professional documents like expense schedules to avoid sharing sensitive internal feedback.
No, when you mark errors using comments and annotations in Acrobat, the original words are not changed. Your marks are added on a separate layer on top of the document. This means the original text stays exactly as it was. You can always remove or hide these marks later without affecting the document's content.
