About Protect PDF

Encrypt your PDFs with a strong password, with precise control over what readers can do.

How to use Protect PDF

  1. 1Subscribe to Starter or above, then upload your PDF.
  2. 2Enter a password and confirm it. The strength indicator guides you — aim for "Strong".
  3. 3Choose the permissions granted to readers: Print, Copy text, Modify.
  4. 4Click "Protect & encrypt". The PDF is encrypted locally, without leaving your browser.
  5. 5Download the protected PDF.

Tips

  • A strong password combines uppercase, lowercase, numbers and symbols (e.g. T3mp$2025!).
  • Disable all permissions for a read-only PDF — readers won't be able to print or copy text.
  • Store your password safely: an encrypted PDF with a lost password cannot be recovered.
