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 puts a colored background over the text, making it stand out like with a marker. Underlining draws a line beneath the text. Both are ways to mark important text for review, but highlighting is often used for main points, and underlining for specific details or emphasis. You can choose whichever makes your notes clearer.
Comments are usually saved within the PDF. If they seem missing, check if the comment panel is hidden or if the document was 'flattened' or 'sanitized' by someone else. Flattening combines comments into the main document, making them uneditable, while sanitizing removes them completely. Always save a copy before sanitizing if you want to keep your review notes.
When multiple people review a document, Acrobat helps by showing all comments in a side panel, often sorted by author or type. You can usually filter these comments to see only specific people's notes or types of markups. This makes it easier to track feedback from different reviewers without getting confused by too many marks on the main document.
