Restrict Editing with Adobe Acrobat
Use Adobe Acrobat's built-in security features to set a permissions password that prevents others from editing the PDF.
This method requires an active Adobe Acrobat subscription to access advanced document security settings. Without a subscription, you may only be able to view files rather than encrypt them.
Launch Adobe Acrobat and open the PDF document you wish to protect.
Navigate to the 'Tools' menu at the top, scroll down to the 'Protect & Standardize' section, and click on 'Protect'.
In the top toolbar, click on 'Protect Using Password' or go to 'Advanced Options' and select 'Security Policies'.
Select the option to restrict editing and printing. Enter a strong permissions password in the designated field and retype it to confirm.
Click 'Apply' or 'OK' to set the security preferences, then go to 'File' > 'Save' to finalize the uneditable status of your PDF.

Frequently Asked Questions
Can I make a PDF uneditable without using a password?
While you can convert a PDF to an image or 'flatten' it to make editing more difficult, the only secure way to prevent editing while keeping the text scalable and searchable is by applying a permissions password.
What is the difference between a Document Open password and a Permissions password?
A Document Open password restricts who can open and view the file. A Permissions password allows anyone to open the file but restricts specific actions like editing, copying, or printing based on the settings you choose.
Will my password protection work if the recipient uses a different PDF viewer?
Yes, standard PDF password protection and permission restrictions are universally recognized by all compliant PDF readers, including web browsers, mobile apps, and third-party software like WPS Office.
