How to password protect a PDF

Adding a password before you share a personal or confidential document keeps the wrong person from opening it.

Steps

1. Tap Protect on the home screen and choose protect mode.
2. Pick the PDF you want to protect.
3. Type a strong password in Password; tap the eye icon to check it.
4. Save, then use Share or Export on the result card.
5. Send the password through a different channel than the file (for example the file by email, the password by phone).

Good to know

• Android uses AES-256; iPhone and iPad use standard 128-bit PDF encryption, the strongest iOS offers. On iPhone the password must use English letters, digits and symbols only.
• There is no way to recover a forgotten password; the app does not store it anywhere.
• The protected file opens with the password in any standard PDF reader.
