- AES 128-bit, 256-bit Revision 5 and 256-bit Revision 6 (PDF 2.0)
Protect with owner password
The owner or master password is used to change the password and to set or restrict access rights of the PDF document. Owner password is necessary to open and view PDF documents.
Protect with user password
The user or open password is required to open and view PDF documents with allowed permissions. Only PDFs with user password are safe from cracking.
Document permission
By customizing the permission settings, allow or restrict users from performing certain actions such as content copying, printing, editing the document, filling form fields, and more. In addition, it is possible to change or remove PDF permissions and passwords.
