Whether you're an employee or a corporation, you'll need to know how to lock a PDF from being edited at some point in time. Perhaps you have some meeting agenda, a contract copy, or confidential information that you need to communicate with a client or a third party. Only approved people should be able to open and interact securely with the material in any situation.
The fact is that there are many simple ways to lock a PDF from editing, but not all of them are equal or secure. This article will go over the quickest and easiest ways to prevent PDF files from being edited by unauthorized users.
When you save a document as a PDF, the format is usually preserved, meaning the content can still be edited and copied. Let's explore methods to protect PDF from editing.
Method 1: Adobe Acrobat DC PRO
Adobe Acrobat DC Pro is the most popular PDF software. You can block users from making changes to PDF files. Users can't edit content, move objects, or create form fields if they have the limit editing option enabled. Users may still complete form fields, sign documents, and leave comments.
Follow these steps to lock PDF from editing:
Step 1: In Acrobat DC Pro, open the PDF and perform one of the following actions:
• Select File > Password Protection.
• Select Tools > Protect > Protect Using Password from the drop-down menu.
Step 2: If prompted, select Yes to alter the security settings.
Step 3: Select Editing from the drop-down menu, then type and retype your password. The length of your password must be at least six characters. The password strength indicator appears next to your password, indicating whether it is weak, medium, or strong.
Step 4: Apply the changes. Acrobat provides a notice confirming that the password-protected file was successfully protected.
