Why You Need a PDF Protector in 2025

PDFs are the #1 format for sharing documents — but unprotected PDFs are a security risk:

• 73% of businesses have experienced data leaks from unsecured files
• Google Drive and email don’t encrypt PDFs by default
• Sensitive info (SSN, bank details, contracts) can be copied, printed, or edited
• Compliance laws (GDPR, HIPAA, FERPA) require document protection

That’s why our PDF protector is essential. It gives you:

🔒 Password protection – only authorized users can open
🔐 Encryption – unreadable if intercepted
🖨️ Permission control – disable printing, copying, or editing
🌍 Global compliance – meets ISO/IEC 27001 standards

Perfect for:

• Lawyers & HR teams
• Accountants & financial advisors
• Students & educators
• Freelancers & agencies
• Small business owners

How Does the PDF Protector Work?

Our tool uses AES (Advanced Encryption Standard) — the same encryption used by banks and governments.

Step 1: Upload Your PDF

Drag & drop or browse any PDF (max 50 MB). Supports scanned, text, and image-based PDFs.

Step 2: Set Security Options

• User Password: Required to open the file
• Owner Password: Required to change permissions
• Permissions: Choose what users can do:
  • ✅ View only
  • ❌ Disable printing
  • ❌ Block copying text/images
  • ❌ Prevent editing

Step 3: Download Your Protected PDF

Get a fully encrypted, password-secured PDF ready to share — instantly.

Example:
You send a client contract.
→ Only they can open it (with password)
→ They can’t copy clauses or print without permission
→ Even if forwarded, it stays locked
