Easy-to-use, only 3 steps to manage PDF security settings
Encrypt multiple PDF files with the same security setting at one time. For example, you can add 100 PDF files, and set a permission password to limit the copying and printing features. Or you can add an open password to all 100 files within a few clicks.
Besides adding security setting, you can also remove security setting if you have the permission to do so.
If you know the open password, enter the open password, then you can remove it from the document, so you don't need to enter the open password every time you open a PDF file.
If the document has a permissions password, you can also remove the permissions directly. So managing the security of a PDF document can not be easier.
Important: If you forget a open password, you cannot recover it from the PDF.
