How to Encrypt PDF Files and Its Purposes.

PDF (Portable Document Format) has become the standard for modern office document exchange. Encrypting PDF files is a crucial method for protecting sensitive information, whether it's business contracts, financial reports, or personal identification data. Encryption ensures that only authorized individuals can access the content.

Purposes of PDF Encryption

  1. Privacy Protection: Prevent unauthorized access and ensure sensitive information isn't compromised

  2. Usage Control: Restrict printing, editing, or copying content to protect intellectual property

  3. Regulatory Compliance: Meet requirements of data protection regulations like GDPR and HIPAA

  4. Secure File Sharing: Ensure file security even when transmitted through insecure channels
