- Scenario
- Securing a PDF document before sharing it to protect intellectual property and prevent unauthorized modifications.

Restrict Editing and Copying in Adobe Acrobat Pro
Use the built-in Document Properties security settings in Adobe Acrobat Pro to set a permissions password.
Adobe Acrobat Pro allows you to set a permissions password (also known as a master password) to restrict certain features like printing, editing, and copying content. This ensures that anyone who opens the document can read it, but cannot modify or extract its contents without the password.
Open the PDF in Adobe Acrobat Pro and go to 'File' > 'Properties' from the top menu. Alternatively, you can press Ctrl+D on Windows or Command+D on macOS.
Navigate to the 'Security' tab in the Document Properties window. From the 'Security Method' dropdown menu, select 'Password Security'.
In the Password Security Settings dialog, check the box that says 'Restrict editing and printing of the document'. Enter a strong password in the 'Change Permissions Password' field.
Under the 'Changes Allowed' dropdown, select 'None'. Ensure that the checkbox for 'Enable copying of text, images, and other content' is unchecked. Click 'OK' to confirm.
Click 'OK' again to close the Document Properties window, then save the PDF file (File > Save) to apply the security restrictions.
Easily Restrict PDF Editing and Copying with WPS PDF
WPS Office includes a powerful PDF editor that allows you to easily encrypt your documents and set detailed permission passwords to prevent unauthorized editing, printing, and copying.
- 1. Open the PDF in WPS Office: Launch WPS Office and open the PDF document you want to secure.
- 2. Navigate to the Protect Tab: Click on the 'Protect' tab located on the top ribbon menu, then select 'Encrypt'.
- 3. Enable Permission Password: In the Encryption dialog box, check the option for 'Set Password to Restrict Editing and Printing'.
- 4. Set Restrictions: Enter your desired permissions password. Uncheck 'Allow copying' and set 'Editing allowed' to 'None'.
- 5. Confirm and Save: Click 'Confirm' to apply the settings, then save your document to finalize the security restrictions.
Frequently Asked Questions
Can someone bypass the PDF editing restrictions?
While permission passwords prevent editing in standard PDF readers like Adobe Acrobat and WPS PDF, some third-party tools or online unlockers might bypass them. For highly sensitive data, consider adding an open password as well.
What is the difference between a Document Open password and a Permissions password?
A Document Open password requires users to enter a password just to view the PDF. A Permissions password allows anyone to open and read the PDF, but restricts actions like editing, printing, or copying content.
Why is the 'Security' tab grayed out in my PDF properties?
The Security tab may be grayed out if the document is digitally signed, certified, or if you are viewing it in a basic PDF reader rather than a full PDF editor like Adobe Acrobat Pro or WPS PDF.
How do I remove the editing restrictions from a PDF?
To remove restrictions, open the PDF in your editor, go to the Security properties, change the Security Method to 'No Security', and enter the permissions password when prompted. Save the file to finalize the removal.
