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 text in a PDF makes it stand out with a colored background, like using a physical highlighter pen. Underlining puts a line beneath the text. Both are types of markup tools used to draw attention to specific words or sentences. The choice depends on personal preference or the type of emphasis you want to create.
Comments do not usually disappear when you save a PDF, as they are part of the document data. However, if you or someone else 'flattens' the PDF, the comments become part of the main document image and can no longer be edited separately. Also, if you use the 'Sanitize' tool, comments are permanently removed. Always check your save settings or if the file was flattened before sharing.
To draw a circle around a mistake in your PDF, you should use the 'Drawing Markup' tools. These tools let you add shapes like circles, squares, or lines directly onto the document. You can find them within the 'Comment' section of Adobe Acrobat.
A 'separate layer' means that comments and markups are placed on top of your original PDF content, but they are not permanently mixed in. Think of it like a clear sheet of plastic placed over your document where you write notes. This allows you to hide, show, or even remove comments later without changing the original text or images underneath.
