- Comment: prevent the user from adding comments to the PDF file.
- Comment – Fill forms: prevent the user from adding comments or edit – fill forms in the PDF file.
Example:
In this example, If the user entered the User password, The PDF will be opened but the user won’t be able to print or copy from the PDF, but entering the Owner password, The user will able to open the file and also grants the print and copy from the PDF.
Note: Both passwords must be set because the PDF can be opened by either on of them so If one password is empty, the PDF can be opened without password. If you don’t want to restrict any permissions, you can use the same password for both.
