How to Password Protect a PDF Free — Encrypt PDFs Online

Why Password Protect PDFs

Financial documents, medical records, contracts, HR paperwork, and confidential reports should not be accessible to anyone who happens to find the file. Password protection ensures only authorized recipients can open the document.

How to Protect a PDF

1. Open the Protect PDF tool
2. Upload your PDF
3. Enter a strong password
4. Download the encrypted PDF

Share the password through a separate channel (text message, phone call) — never send the password in the same email as the document.
