Protect PDF

Encrypt your PDF with an opening password using AES-256 encryption.

Choose a PDF up to 20 MB and enter a password (at least 8 characters).

Encryption happens on the PDFied server. The PDF is transferred to the server for processing and is not intentionally stored by this implementation. Use HTTPS when deployed. Keep a copy of the original and store your password safely.

How it works

PDFied applies genuine AES-256 PDF encryption. You will need the password to open the downloaded file. Files containing unsupported PDF features may be rejected rather than silently altered.

This feature requires the included Python server and PyMuPDF. It does not work from a file:// address or static-only hosting.
