About Protect PDF
Encrypt your PDFs with a strong password, with precise control over what readers can do.
How to use Protect PDF
- 1Subscribe to Starter or above, then upload your PDF.
- 2Enter a password and confirm it. The strength indicator guides you — aim for "Strong".
- 3Choose the permissions granted to readers: Print, Copy text, Modify.
- 4Click "Protect & encrypt". The PDF is encrypted locally, without leaving your browser.
- 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.
