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 makes text stand out by coloring its background, like with a marker. Underlining places a line directly beneath the text. Both are ways to draw attention to specific words or sentences. Highlighting is often used for key information, while underlining can indicate emphasis or a need for review.
You should sanitize a PDF to remove hidden data like comments, annotations, and metadata before sharing. This is important because comments often contain private notes or discussions that are not meant for the final audience. Sanitizing ensures that only the intended content is visible, protecting sensitive information and presenting a clean, professional document. It prevents accidental leaks of internal review notes.
No, adding comments to a PDF does not change the original text of the document. Comments and annotations are added as a separate layer on top of the PDF. Think of them like sticky notes or transparent overlays. The original content remains untouched, which is why you need to 'flatten' or 'sanitize' the document if you want to remove these layers permanently.
Drawing markup tools in Adobe Acrobat let you add shapes, lines, or freehand drawings directly onto a PDF. You would use them when you need to visually point out specific areas or elements that text comments cannot easily describe. For example, you might use a circle to highlight an image, draw an arrow to indicate a specific section, or use a pencil tool to sketch a quick correction on a diagram. They are great for visual feedback.
