Protect your documents before you send them
Adding a password to a PDF is the simplest way to email statements, contracts or medical records without letting just anyone open them. We use 256-bit AES encryption, the strongest PDF standard, supported by Adobe Reader, Chrome, Edge and most readers.
Encryption runs in your browser with qpdf, an open-source tool. Neither the document nor the password ever leaves your device.
How to password protect a PDF, step by step
- 1
Select the PDF.
- 2
Enter the password twice and, if you like, block printing, copying or editing.
- 3
Download the protected PDF and share the password through a different channel.
Frequently asked questions
What if I forget the password?
It can't be recovered: 256-bit AES is designed so nobody can open the file without it. Store it somewhere safe.
Are the print and copy restrictions secure?
Adobe and most readers respect them, but some programs ignore them. The open password, on the other hand, is always required.
How should I send the password?
Through a different channel than the file: for example, the PDF by email and the password by text message or phone call.
