pdf1 Use ‘PDF Unlocker’ to crack open Password Protect PDF files and Remove RestrictionsPDF is a great format for distributing and sharing documents as it can keep the originality of the documents. Most of the files (manuals, tutorials, etc.) downloaded from the internet are usually in PDF format. You can use PDF reader to open such files and read them. However on some occasions, you may experience difficulty in opening, copying or/and printing text from the PDF files due to restrictions imposed by the owner and this is where ‘PDF Unlocker’ comes handy.


The PDF files can be protected by applying ‘user password’ or ‘owner password’. If a PDF file is protected with ‘user password’, the owner can prevent others from opening the file. For preventing printing and copying of text and graphic, do modifications, etc, the owner can put a ‘owner password’. File protected by both the ‘users’ and ‘owner’ password are hard to crack and force open. However, ‘PDF Unlocker’ can be brought to rescue in such a case.

‘PDF Unlocker’ is a free tool that can be downloaded here. Once downloaded and installed, you can create a ‘PDF Unlocker’ shortcut icon on the desktop. To unlock the ‘owner’ password, what you need to do to unlock the file is just drag the protected file to the PDF Unlocker icon. Immediately the tool will decrypt the owner password and remove the restriction imposed on it. You will then be allowed to print, copy, modify, etc. To unlock the restriction imposed by ‘user’ password, users have to right click and select “Remove PDF Password” and close the application.

If the PDF has been set the restrictions that prevend people copying and printing, we can just change PDF to Word using AnyBizSoft.

But it must be legally of course.
But cracking the so-called user password, which prevends people from opening the PDF, I really have no idea.
