Why PDF Security Matters More Than Ever
In an era of data breaches and digital theft, protecting sensitive documents is not optional — it's essential. Whether you're sharing a confidential business proposal, a legal contract, or personal financial documents, PDF security gives you control over who can access, print, or modify your files.
Types of PDF Protection
1. Open Password (User Password)
An open password is required to open and view the PDF file.
When to use: Sensitive reports, personal financial documents, confidential contracts.
2. Permission Password (Owner Password)
Defines what actions are permitted on a document that can be opened:
- ✅ Allow viewing but prevent printing
- ✅ Allow reading but prevent copying text
- ✅ Allow viewing but prevent editing or annotations
3. PDF Encryption
PDF encryption (128-bit AES or 256-bit AES) scrambles the file data so it can't be read without the password.
256-bit AES is recommended — compatible with Acrobat X and later.
