Frequently asked questions
How strong is the encryption?
The PDF is encrypted with a password so it can't be opened without it. Choose a strong, unique password — anyone with it can open the file.
What happens if I forget the password?
There's no recovery. We don't store your password, so keep it somewhere safe before you close the tab.
