Why protect PDFs

Password protection stops casual openers from reading sensitive attachments if an email is forwarded by mistake.

Step-by-step

  1. Open Protect PDF on LitePDF Pro.
  2. Upload the PDF.
  3. Enter a strong password and confirm it.
  4. Download the encrypted PDF.
  5. Share the password through a separate channel when possible.

Unlock later

If you still know the password and need an open copy, use Unlock PDF. We cannot recover forgotten passwords.
