This program (Advanced PDF Password Recovery, or APDFPR) is intended to decrypt password-protected and restricted Adobe Acrobat PDF files, which have “user” password set (required to open/view the file), and/or “owner” password (when the file is only protected from editing, printing etc), i.e. remove the protection and/or break the PDF password.

Restricted files are being unprotected instantly, while decryption of files with “open” password may be time-consuming. The program is also able to convert Kinko’s Document Format (KDF) files to PDF files (without any protection).
