From highlight, stamp, note, pencil, to shape, you can find common annotating tools in SwifDoo PDF. Once you have added annotations to a PDF document, these marks will always remain active regardless of any operating systems.
You can directly reply to others’ annotations. At the same time, you can choose the status of your reply, such as Accept or Deny. It is quite easy to start conversations between reviewers and recipients. Besides, SwifDoo PDF has a Manage button to view all annotations.
Multiple stamps are available to label the document, such as the document’s approval status or confidentiality level. We provide different stamps for users to indicate the status of the PDF files.
