Sensitive documents — contracts, statements, IDs — shouldn't travel unprotected. Adding a password encrypts the file so only people who know it can open it.
Protect a PDF
- Open Protect PDF.
- Upload your file and choose a password.
- Download the encrypted PDF.
It's encrypted in your browser, so the file and password never leave your device.
Tips
- Use a strong, unique password — generate one with the Password Generator.
- Share the password through a different channel than the file (e.g. text the password, email the PDF).
- To remove a password later, use Unlock PDF.
