Phones, computers, laptops, and even the files saved in them are nowadays preferred to be protected with the password. Reason being, it gives the owner a sense of contentment that the data cannot be accessed by anybody else without their permission.

To some extent, such theories prove to be quite helpful but there are times when passwords can actually trouble the user. For example: To make our passwords unique so that no one can crack them, we generally generate an alphanumeric code that can have upper or lower case characters. Just imagine that you forgot the password! Now what?

In the case of PDF, there is a special kind of password protection that is set to assure that no one can misuse the file data. Usually, what we do is we set open document password. This means unless the security code is entered, the file cannot be opened. In the case of Adobe PDF, this is termed as User Password. Another type of protection is a master password where anyone is allowed to open the file, but is restricted to make any changes in it. For example, it is not possible to copy, print, or edit the contents of the file. This is called Owner Password for Adobe PDF file.

To rescue such scenarios, there are tools available online that can help to remove password from a restricted PDF file. We are going to discuss one such tool here which is named as PDF Unlocker software.
