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.
A sticky note is like a small digital note you can place anywhere on the document, often used for short remarks. A text box lets you type more text and can be resized or moved. Both are good for adding notes, but text boxes offer more space and formatting control for longer explanations directly on the page.
Comments themselves don't disappear, but sometimes they are not visible if the recipient's PDF viewer is not set to show comments, or if the file was 'flattened' without your knowledge. Comments are a separate layer. To ensure visibility, always tell recipients to enable comment viewing. If you want to make comments permanent and uneditable, you might need to 'flatten' the PDF yourself, but this makes them part of the main document and no longer separate, editable notes.
Sanitizing a document means removing all hidden information, including comments, metadata, hidden layers, and other review notes. It's a crucial step before releasing a 'final' file to prevent sensitive information or internal review discussions from being seen by unintended recipients. Unlike flattening, which merges comments into the document, sanitizing permanently deletes them and other hidden data to ensure a clean, secure file for public sharing.
