Advanced PDF Protector can secure PDF documents with user and owner passwords. It automates the task of protecting PDF documents with user (document open) password, owner (permissions) password and various PDF security permissions.

The application automatically imports all unsecured PDF documents from a specific directory and all of its subdirectories. Alternatively, users can manually import PDF documents that need to be secured. For each imported input PDF document the application creates a secure copy of the original PDF file. Advanced PDF Protector provides users with an interface to select output PDF version, assign optional user (document open) password, assign owner (permissions) password and allow / disallow high-resolution printing, low-resolution printing, commenting, form field fill-in or signing, content copying, document assembly or changing in the output PDF files. In addition to this, the application automatically persists most recently used input and output directory paths and allows users to sort input PDF files by path, size and creation date. Download sample output PDF file with PDF security restrictions, user (document open) password "password1" and owner (permissions) password "password2".
