Advanced PDF Protector automates the task of protecting PDF documents with 128-bit encryption, various security permissions and passwords. The application automatically imports all unencrypted PDF documents from a specific directory and all of its subdirectories. Alternatively, users can manually import PDF documents that need to be encrypted. For each imported input PDF document the application creates a 128-bit encrypted copy of the original PDF file. Advanced PDF Protector provides users with an interface to select output PDF version, enter user and owner passwords 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.
