If you ask me what the most annoying thing in my work is, I should say PDF password. I have to deal with many forms, applications, reports and contracts in PDF in my daily work, but many of them are restricted by PDF password. My goal is very clear—to crack PDF password, but it's a bitter experience to spend the whole morning to search for a method to open or copy or edit or print a PDF file. After many painful trials, I conclude 3 things you should decide before cracking PDF password.

Decide Which PDF Password It Belongs to

In order to tackle with the problem, you need to know which PDF password it belongs to—user password (also known as open password) or owner password.

If a dialog box pop up and request you to enter a password when opening a PDF file, then the PDF file must be protected by user password.

However, if a PDF file allows you to open it, but does not allow copying, editing or printing, then you can decide this is owner password. You cannot underline keywords, highlight good sentence, cross out words or make any changes in this PDF file.

Decide Why You Need to Crack PDF Password

You can't open the PDF file without entering the right user password. You can first recall, guess or simply ask the sender of the PDF to get it. However, what if the sender is away for vocation? What if you can't recall the password you set by yourself? In this situation, don't wait for that the right password would come to your mind all of a sudden. Crack it immediately!

For owner password, even you recall it or the sender tells you the password, you have to use an app, for example, Adobe Acrobat, to reset it. The restriction settings cannot be done in PDF readers. You have only two choices: reset it or simply crack it. In most situations, we choose the latter as it's easier.

Then it comes to another question, what apps you can use to reset or crack PDF password?
