Forget the PDF password and cannot access to your PDF documents? Tried several PDF Password Remover but got to nowhere? Don’t be upset, I am going to show you the right moves to do when you forgot PDF password.

First of all, find out which PDF password protects your PDF.

As we all know, there are 2 PDF password used to protect your PDFs: User Password and Owner Password.

User (Open) Password: protecting PDF file from opening

Owner (Master) Password: protecting PDF file from any changes on editing, from copying, printing, reading by screen readers, etc.

In another words, 

  • If you cannot open a PDF file, your file is user-password protected, and you need to crack/restore PDF User Password;
  • If you can open the PDF file, but are restricted to edit, copy or print, your file is owner-password protected, and you need to crack/restore PDF Owner Password;
  • If you cannot open or edit the PDF file, your file is both user&owner password protected, and you need to crack/recover both PDF user and owner passwords

Then, decrypt or recover your PDF password.

But how?

As information becomes an ever aggravating factor that shapes how better we solve problems, we often return to Internet for solutions. So, most of our PDF users are inclined to seek answers from Google, and we find 2 general types to deal with forgotten PDF password decrypt (directly crack the pdf password) or recover (find back your pdf password) it.
