Open your PDF file in Adobe Acrobat.

Comments are usually text-based notes, like a sticky note or a text box, where you write your thoughts. Markups are visual changes to the document itself, such as highlighting text, underlining words, or drawing shapes. Both help you give feedback, but comments add new text, while markups change how existing text or images look.
Yes, if you share a PDF that has comments and annotations, others who open it will be able to see all your notes, highlights, and drawings. This is because comments are saved as a separate layer on top of the document. If you do not want them to see your notes, you must 'flatten' or 'sanitize' the PDF before sharing. This removes all the review data permanently.
You should sanitize a PDF before making it 'final' to prevent your review notes and comments from being seen by others. Comments are often recoverable data, meaning they can be found even if they seem hidden. Sanitizing removes all these hidden layers of feedback, ensuring that only the final content is visible. This protects your privacy and prevents accidental sharing of internal discussions or sensitive information.
