Forgot PDF password? Not a matter of embarrassment. Password recovery is quite an everyday issue that can happen to anyone. Although PDF files have a high level of security and it is challenging to encrypt them, we work hard for you and find effective and practical hacks of recovery.

In this article, we will provide you with solutions on how to crack PDF password. We are listing down some ways to bring you out of the hassle of password recovery.

But before going to unlock these methods, you should know the type of your file password. There are two types of passwords.

1.  PDF document open password is also known as user password

2.  PDF master password is known as PDF owner password

It is essential to have knowledge of both types of passwords. In the owner password, the user is only allowed to open and view the PDF file. So if you forgot the owner password, then you have minimal access to your document. You can’t copy, edit and open the file.

On the other hand, the user password prevents people from viewing and copying the PDF file. The user password is added while creating the PDF file. This password is mainly applied when information is highly confidential.

 Some of the listed methods provide the solution for both types of passwords.
