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 directly marks specific words or sentences, drawing attention to them without adding extra space. It's good for quick emphasis. A text box comment, however, lets you write a longer note or question in a separate box, often placed in the margin. This is better for detailed feedback or explanations related to a section of text, rather than just marking the text itself.
It is important to sanitize comments because they are recoverable data, even if they appear hidden. If you share a final PDF without sanitizing, your private review notes, questions, or internal discussions could accidentally be seen by others. Sanitizing ensures that all comments and markups are permanently removed, protecting your privacy and presenting a clean, finished document without any internal review history.
If you want to add a drawing to mark a specific area on a PDF, you should use the 'drawing markup' tools. These tools let you draw shapes like circles, arrows, or freehand lines directly on the document. This is useful for pointing out visual elements or areas that need attention, rather than just text.
Reaction emojis are small icons, like a thumbs-up or a smiley face, that you can add to comments during a shared PDF review. They help by allowing you to quickly show your agreement, disagreement, or other feelings about a specific comment without typing out a full response. This makes group reviews faster and more interactive.
