If you are struggling with Opening a Password Protected PDF, you can use Freeware PDF Unlocker to remove the password protection from the PDF and use it like any other PDF.

Usually PDF passwords are of two types

Type 1 A password that restricts some functions. Such as printing, copy & paste. This is the most common type of password set.

Type 2 A password to open the file for reading the PDF. This kind of password is usually set in PDF’s sent by banks, mutual fund companies etc.
