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.
Comments are general notes, like sticky notes or text boxes, that you add to a PDF. Annotations are specific types of comments that mark or highlight parts of the document, such as underlining text, striking through words, or drawing shapes. Both serve to add feedback without changing the original document content, but annotations are more about direct visual marking.
Comments might seem to disappear if the person you share with is using a different PDF viewer that doesn't fully support Acrobat's comment features, or if the comments layer was accidentally hidden. To ensure comments are always visible, you can 'flatten' the PDF before sharing. Flattening makes comments a permanent part of the document, so they cannot be hidden or removed easily. This is different from sanitizing, which removes them.
| Feature | Comments & Annotations | Editing Original Text |
|---|---|---|
| Original Content | Keeps original text untouched, comments are a separate layer. | Changes the original text directly, potentially losing previous versions. |
| Collaboration | Allows multiple reviewers to add feedback without conflict. | Can lead to version control issues and overwriting changes. |
| Purpose | Ideal for suggestions, questions, and non-permanent feedback. | Used for final changes and corrections to the document itself. |
