Now-a-days, we often get email containing payslip, credit card transactions statement, monthly bank account transaction summary, mobile bill, confidential office document etc. in a PDF attachment. Such PDFs are encrypted and securely protected with strong passwords as those contain personal information. But it is not possible to remember the security password of each PDF file, the passwords are different and complicated. As, the PDF files are secured, if you save those files to Google drive, they will not be searchable anymore. So, it will be better to remove security password from the PDF file and then save it to your cloud storage. The Google drive cloud storage gives two-step security (password and two-step authentication), so, there will be no chances for privacy theft.
You can apply different methods to bypass security password from PDF. You can try online or offline method. Offline method requires software to unlock PDF. And, if you try to remove such security online, then you can take help of PDF password remover website to complete the task.
Before going to next stage, I want to inform you that two types of passwords can be used to protect a pdf document.
Owner Password: Owner can protect a PDF document from further editing by using such password. In this case, a user can easily view, share or print the file. But, user will be asked for admin password before modifying the document.
User password: User password is required to open, view or print the PDF. In this tutorial I will discuss about this kind of security.

Method #8: Unlock the PDF Password When You Lost it or Don’t Know it
If reasons are genuine, you have legal rights to crack PDF security password. As, I have mentioned earlier that there are two types of passwords that can be used in order to secure any PDF. If the administrator of the file protects the PDF from editing using a password, you can easily view the document and unlock it using any OCR software or Chrome or using something else. But the cases are different when you don’t have the access to view file. So, you need to use methods like Brute Force, Dictionary attack, Key search etc. to get the actual password. These methods are time taking and these might take even days depending upon the processing speed of the computer to uncover the password combinations. You can try Advanced PDF Password Recovery from Elcomsoft to perform the task. The software will display the password as soon as it will be found.
