PDF files are widely used for sharing sensitive information because they support password protection. At the same time, there are moments when you need to remove a password for easier access or sharing. In this article, we'll guide you through the process of adding or removing passwords from PDF files using free tools, desktop software, and best practices for security.

  • Academic research and exam papers
  • Personal documents like IDs and certificates

🔑 Types of PDF Passwords
