This runs in the Acrobat app - there is no separate API for this task.
Highlighting text simply changes the background color of existing text to draw attention to it, without adding new words. A text box comment, however, lets you type new words or sentences anywhere on the page, separate from the original text. You use highlighting to mark what's already there, and a text box to add your own thoughts or explanations.
Comments and markups are important because they allow you to give clear feedback and suggestions directly on the document without changing the original text. This makes it easy for others to see exactly what you are referring to and understand your points. They help make the review process efficient and ensure everyone is on the same page for revisions.
No, adding drawing markups will not change the original content of your PDF. Comments and markups are added as a separate layer on top of the document. This means the original text and images stay untouched. You can add lines, shapes, or other drawings without affecting the core information.
Reaction emojis on shared reviews help you quickly show your feelings or agreement about specific comments or parts of a document. Instead of typing a full response, you can use an emoji like a thumbs-up or a smiley face to give instant, simple feedback. This makes communication faster and more informal during a review process.
