This runs in the Acrobat app - there is no separate API for this task.
Comments and annotations are ways to add feedback, notes, or marks to a PDF document without changing the original text. They act like a transparent layer on top of the document. This is useful for reviewing, suggesting changes, or asking questions directly within the file, making collaboration easier.
You should sanitize your PDF to protect privacy and prevent information leaks. Comments and annotations are often review notes that might contain sensitive or internal feedback. Sanitizing removes this extra layer of data, ensuring that only the final, approved content is shared. This prevents unintended recipients from seeing draft discussions or private remarks that were not meant for them.
Yes, if you share a PDF that has comments and annotations, others who open it in Adobe Acrobat or a compatible PDF reader will be able to see your notes. These comments are part of the file's data. This is the main purpose of comments: to share feedback directly within the document for others to review and respond to.
