There are a lot of PDF files can not be printed or converted, that means those PDF files have been protected. PDF Password Remover is a tool to remove PDF restrictions from protected PDF files on Windows and Mac OS X.
Before removing the PDF owner password and restrictions, you do not have the authority to convert, modify and print the PDF document. After PDF Password Remover processing, the protected PDF document will be decrypted to a normal PDF file and you can do anything on it.
If you are a Mac user, please download the installation file here (10 MB).
