PDFKey Pro is used by simply dragging one or more files, or even an entire folder, onto the PDFKey Pro. You can even use it in shell scripts or with Automator (Mac OS X Only).

PDFKey Pro reads your PDF files with printing or copying passwords set and then creates exact replicas of the PDFs, but without the passwords.

For PDF files that have a viewing password set, PDFKey Pro will read your PDF file and create an exact replica of the PDF without any password, although you must supply this password beforehand.

Locking is as simple as unlocking. You will be prompted with a dialog to set your passwords and an exact, but protected, copy of the PDFs will be created.

The included command line and Automator actions (Mac OS X only) features allow you to insert PDFKey Pro in complex workflows. PDFKey Pro can process entire folders of PDF files without requiring user intervention.

* Recover Documents: Unlock PDF documents protected for printing and copying when you've forgotten your password.

* Lock PDFs: Lock PDF document with a password, restrict usage permissions on your documents.
* Automate: Batch-process multiple PDF files or folders without additional input. Use the included command-line tool or Automator actions (Mac OS X only).
