How to Change the Security Settings in PDF
In today’s digital age, PDF files have become a staple for sharing and distributing documents. However, with the convenience of PDFs comes the need for security. To protect sensitive information from unauthorized access, it is essential to change the security settings in PDF files. This article will guide you through the process of modifying these settings, ensuring that your PDFs remain secure.
Understanding PDF Security Settings
Before diving into the steps to change the security settings, it’s crucial to understand the different types of security features available in PDF files. These features include password protection, permission restrictions, and digital signatures. Password protection allows you to set a password that must be entered to access the PDF. Permission restrictions, on the other hand, limit the actions users can perform on the document, such as printing, copying, or modifying the content. Digital signatures provide a way to verify the authenticity and integrity of the document.

6. If you want to set permission restrictions, click on the “Edit Permissions” button.
7. In the Permissions dialog box, you can specify the allowed actions, such as printing, copying, modifying, or filling in forms.
8. After making the desired changes, click “OK” to save the settings.
9. Finally, click “OK” again in the Properties dialog box to close it.
