Recover PDF Password is a Mac OS X app that will help you recover passwords for PDF files in case they were lost or forgotten.

Recover PDF Password unlocks both user and owner passwords for PDF files. So you will be able to open password-protected PDF, print, edit and copy it.

If your PDF file is protected only with owner password you can use "Decrypt" option and create an unprotected copy of PDF file even without searching for the password.

This program features various methods of passwords recovery: by password length, by template, by dictionary, and exhaustive search method. Dictionary search is the time-saver in case you can remember that the password is a word or a word combination or modification.
