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.
| Comment | Markup |
|---|---|
| A note, like a sticky note or text box, added to explain or ask something. | A visual change, like a highlight or line, to show important parts. |
| Used for explanations or questions. | Used to point out or mark areas in the drawing. |
Comments and markups are saved in a separate layer in the PDF. If you do not remove them, others may see your review notes or private feedback. This can lead to confusion or sharing information you did not mean to share. Before sending a final drawing, always sanitize the file to keep only what is needed.
If you only highlight lines, others may not know why you marked them. Adding a text comment or note helps explain what is important. Using both highlights and comments makes your meaning clear.
