How to Change PDF Password | Explore the 2 Possibilities

Part 1. What Are the Types of Passwords for PDF Documents?

Before you search for a way to alter the passcode, learn what type of lock is on your document. PDF security relies on passwords that serve different purposes to ensure files remain protected from unwanted access or modifications. Knowing the main types of passwords helps apply the right security settings based on specific needs. Furthermore, it aids in learning how to change passwords in PDF.

01of 021. Open Password (User Password)

This type of password acts as the first line of defense for a PDF. Without entering the designated lock code, no one can open the document. It is often used for confidential files, ranging from financial reports and legal contracts to personal records. The aim is to guarantee that only the ones you want can view the content. This type of protection is a must when sharing sensitive information online.

02of 022. Permission Password (Owner Password)

Instead of preventing access, this password controls what actions users can perform once the file is opened. It can restrict editing, printing, copying text, or even completing forms. Even if someone has access to the file, their ability to alter content depends on knowing the specified passcode. It is useful for businesses, legal documents, and academic papers where the content must remain unchanged.

Part 2. How To Change Password in PDF If You Know the Password

When you already know the lock code, altering it is a straightforward process. You might want a stronger password or need to update security settings; both can be done using reliable tools. This section will explore how to change the PDF password using two trusted methods. These tools allow you to unlock the file, update the password, and re-secure it with new credentials:
