About Protecting PDF Files

What is PDF Protection?

PDF protection adds password security and permission restrictions to documents. Control who can view, edit, print, or copy your PDF content, safeguarding sensitive information and intellectual property.

Why Protect PDFs?

  • Confidential Data: Secure sensitive information
  • Prevent Editing: Lock content from modifications
  • Control Access: Restrict who can view documents
  • Copyright Protection: Prevent unauthorized copying

Protection Options

Multiple security levels available:

  • Open Password: Require password to view
  • Permissions Password: Restrict editing and printing
  • Encryption Strength: 128-bit or 256-bit AES
  • Granular Controls: Specific permission settings

Best Practices

Use strong passwords with mixed characters, never share passwords via email, keep backup copies of passwords securely, and review permissions regularly.
