Why You Need to Apply Password to PDF Files
There are several reasons why applying a password to a PDF file is necessary. Let’s take a look at some of the key benefits:
1. Data Security: Password-protecting your PDF files adds an extra layer of security, ensuring that only authorized individuals can access and view the content. This is particularly important when dealing with confidential or sensitive information.
2. Confidentiality: If you’re sharing important documents with others, applying a password to the PDF file ensures that only the intended recipients can open and read the content. This helps maintain the confidentiality of the information shared.
