Protect PDF — questions
What does password protection do?
The PDF becomes unreadable without the password — anyone who opens it is asked for the password first. Optionally, printing and copying can also be restricted.
What if I forget the password?
There is no way to recover or remove a forgotten password — that's the whole point of encryption. Write it down somewhere safe before downloading.
Is my password sent anywhere?
No. The encryption happens entirely in your browser — your PDF and your password never leave your device.
