For some security reasons, many of the PDF files we come across are password-protected, just like some academic papers or network magazines. If you want to edit them or reuse them, you would better unlock them – secured PDF files first. Because secured PDF files would cause some inconveniences. The question is how to unlock PDF files.
In this very beginning, here is one thing you may want to know - how encryption works:
Generally speaking, a secured PDF may be protected with two following types of password: user password and owner password.
User password protects the files from being opened by anonymous while Owner password protects the files from being copied, printed or edited.
Then how to unlock PDF? A spell would certainly not help. But, a call or simply a message would do. Contact the writer, if you can. However, we may not have the access to the author all the time. And most of PDF files you don’t even know the sources, not to say the writer - We need tools.
You would get a lots of recommend tools in the Internet if you search ”unlock PDF tools”. Here in this article, I would like to list three most popular kinds of tools to unlock PDF files - three most efficient way.
1. Adobe Acrobat
Surfing in the PDF history, you would find Adobe and its sword in Creating and modifying PDF files - Acrobat. And yes it creates PDF file standard and privacy - password and restrictions. So the first tool I recommend is Acrobat.
2. Online tools
Online tools are quite convenience to remove PDF restrictions and owner password. If your PDF files could not be printed, copied, merged or edited, you could surely try them. On the other hand, they couldn’t remove open password. (Privacy issue?)
Simply do a search “unlock PDF” on google would get your job done. And I pick one here: unlockpdf.com. Though, I don’t have enough time to do the review because I didn’t get my PDF back yet.
3. Desktop tools specify on unlocking PDF
Desktop tools again? As Adobe Acrobat is so a giant tool that people would find it is not cost-effect just to unlock PDF files. And most of time, it is not affordable as a normal user.
Here we get cheaper alternatives to Adobe Acrobat that specify on unlocking PDF. I pick Wondershare PDF Password Remover to unlock PDF files, it meets our needs perfectly. Simple interface, extremely easy to use, smart process, removes both open password and user password within seconds, Cheap.
Note: To remove open password, you have to know the open password first. It don’t crack PDF password.
Finally, if we selected the right way, the right program, we would find that unlock PDF and edit secured PDFis not such a complex work as we think it is. Pick the right tool doesn’t make people wise, but it does solve the problem in the most efficient way.
Human differ from animals because of their ability to speak and use tools.
