How to Add Passwords and Encrypt PDF Files?

PDF files are widely used for sharing documents because of their compatibility across devices and platforms. However, when dealing with sensitive information, it’s essential to secure your PDFs with a password and encryption. Adding a password ensures that only authorized individuals can access the file, while encryption protects the contents of the file from unauthorized access. This article will guide you step-by-step on how to add passwords and encrypt PDF files.
