Password Protect PDF: what to know
Add an opening password to a PDF using AES-256 encryption in your browser. A recipient needs that password to open the protected result in a compatible PDF reader.
Password protection controls access to the file; it does not stop an authorized reader from sharing its contents. The password is not recoverable by JustYourPDF. Keep it in a safe place and share it separately from the document.
Popular uses
- Protect a document before sending
- Restrict access to a saved PDF
- Add a password to a sensitive attachment
Tips for the best result
- Use a strong password that you do not reuse elsewhere.
- Open the protected result once to confirm the password before deleting any backup.
