How to Easily Remove Password from PDF: 3 Easy Methods

If you’ve ever forgotten your PDF file password or received a password-protected PDF and wanted to modify it, you know the importance of removing the password from a PDF.

In this article, we’ll show you three methods: using Adobe Acrobat, Google Chrome, and the free online tool ONEPDF. Join us and learn how to get full access to the restricted PDF. Let’s get started!

Using Adobe Acrobat Pro DC

Adobe Acrobat Pro is a recognized PDF tool for people to create, convert, edit, and share PDF files. Decrypting a PDF is just one of the many features it offers.

If you have it installed on your computer, follow these simple steps to remove the password from a PDF document:

  1. Open the password-protected PDF in Adobe Acrobat Pro.
  2. Enter the password when prompted to unlock the file.
  3. Click on the “Lock” icon on the left side of the window.
  4. Select “Permission Details” from the menu.
  5. In the “Security Method” box, choose “No Security”.
  6. Click “OK” to remove the password.

It’s that easy. Now you can view the PDF without entering a password. Note that for the PDF file with a Document Open password, you must input it first to gain access and then remove the security settings.

For the PDF file that only has a permissions password, type the correct password in the “Enter Password” box and click “OK” to remove the restrictions.

Adobe Acrobat Pro boasts impressive features, but comes with a price tag. If you work with PDF files on a regualr basis, it’s definitely worth considering investing in this software.

We highly recommend encrypting important PDF files and keeping your password in a safe place to prevent any unintended limitations.
