How to unlock password protected PDF files

Last updated on November 7, 2017 by

Portable Document Format, which is also known as PDF, is one of the commonly used file type across the Globe. It can be used to encapsulate nearly all the important information including text, graphics, forms, etc into a document with a fixed-layout. Usually, users would like to use it to store and transfer important or confidential contents. In order to keep the PDF document safe or private, the owner of it may lock it with password. If you need to view or edit a locked PDF file urgently, how can you do that? Here are the easy ways to unlock PDF files.

Unlock a PDF file with the online tools

Supposing that you have the desire to open a secured PDF file, but you don’t like to download any third-party applications, you can try these web-based tools. There is only a little difference between the two tools we discussed below. So you can choose either of them depending on your needs.

PDF UNLOCK

PDF UNLOCK is an online service which has a not very decent interface. This tool is compatible with Windows, Mac OS and Linux operating systems. No registration or installation required. All you need to do is to click on “My computer”, “Dropbox” or “Google Drive” to load your file. After selecting your file from your hard disk, then click on “Unlock” button. It will start to help you process it soon. Then you will see a prompt which requires you enter the password of the protected file. Simply enter the password into the box and click on “Unlock” button again. Though it seems to be very simple to use the service to unlock PDF documents, there are some limitations of using it.

PDF UNLOCK

Cons of it:

  • If your file size is more than 5MB, you are not allowed to use the tool for unlocking it. Otherwise, you need to pay $2.99 one time for downloading the unlocked copy of your file.
  • You may be annoyed by the advertisements while using the service.

FreeMyPDF

FreeMyPDF is another free online PDF unlocker that you can use to unlock PDF file. Just like the first one, it is also powered by internet. And the good thing about this tool is that it can handle as big as 400MB file maximum, which is awesome. To unlock a PDF file you can simply click on “Choose File” to import the file you want to process. Once selected, click on “Do it!” button and you are ready to go. Before you are going to test it, please pay attention to its cons.

FreeMyPDF

Cons of it:

  • It is only available to handle the PDFs that can be opened without using any third-party plugins.
  • The service can’t help you unlock the PDF that is encrypted by password.
