In order to about all these possible ways to allow commenting on a PDF file, read the blog.

PDF is the most popularly used document format across the globe. A variant type of security feature can be applied by the users to keep their PDF documents safe from unauthorized access.

There are two types of security available that one can apply. One is open password security which is applied to prevent the opening of a document. Another is applied to restrict any operation on PDF files like print, copy, comment, edit, etc. It all depends on the choice of a user and what type of security he or she wants to use.

However, passwords for both types of restrictions are different. So, when a user wants to allow commenting on PDF when not allowed, a permission password or owner-level password is required.
