Secured PDFs are essential for everyone and come with the highest level of security for an extra layer of PDF protection, especially for business reasons. This PDF security helps protect copyrighted documents and gives you control over who can view, edit, and print them. But what if you forget the password and urgently need an unsecured PDF to read, copy, or modify it?

If you are running out of solutions on how to unlock a secured PDF, this post guides you through some of the easiest methods to unsecure a PDF effortlessly. Stay tuned to learn how to remove security from PDFs using some simple methods with detailed processes.

What Is a Secured PDF?

A secured PDF is typically a protected PDF. Such PDFs restrict users from changing the file content or performing any actions on it. It can either be encrypted or require a code to access the file. These PDFs are primarily used in organizations and are valuable for legal and commercial contracts to ensure trust and authenticity with clients.

There are generally two types of PDF passwords: open password and permission password.

An open password or user password restricts opening a PDF file. Unless the password is entered, you cannot even read the document.

A permission password, also known as an owner password, is used by the document's creator to protect copyright. It lets you only view the PDF but does not permit you to edit, print, or copy the contents.

How to Check If Your PDF Is Secured or Not

Here’s how you can check whether your PDF files are secured.

Step 1: Launch Adobe Reader and double-click the file to open. If you have a password-protected file, enter the password into the popped-up dialog box.

Step 2: Select the File menu and choose Document Properties. Tap the Security tab in the appearing window.

Step 3: Examine your document's security limitations and view the Document Security summary at the top for basic PDF security info. For further security details, click Document Restrictions Summary at the bottom.

Step 1: Double-click the required file's icon and open your secured PDF in Adobe Reader.

Step 2: Enter the file password into the prompt and tap OK to unlock the PDF.

Step 3: Tap the Document drop-down menu and then the Security icon. Click Show Security Properties from the appearing list.

Step 4: Tap the Permissions tab and choose Edit. Remove the password and select Apply to unencrypt your PDF document.
