Often PDF files, especially those downloaded from the internet, are protected by passwords. You're asked to enter the password each time you want to view the document. This is done to prevent the files from being opened, edited, and printed by unauthorized users.
However, it can be annoying for the rightful owner of the PDF to forget or lose the password. In such cases, you can use password remover tools to get access to your PDF documents.
Types of PDF Passwords
There are two types of passwords used to protect PDF files:
- Owner Password: It's not mandatory to know the owner's password to open and view a PDF file. This password is created so that the owner can make changes to their PDF document. In case you don't have the owner's password, you will have restricted access to the document. You might not be able to print, edit, or copy. However, with the right software, this type of password can be removed.
- User Password: Also known as an open password, it is only used to prevent people from opening and viewing a PDF file. You cannot access or open a file without the correct password.
