Questions
What if I forget the password?
It cannot be recovered by anyone, including us. Keep a copy of the unprotected file somewhere safe.
Is the password sent anywhere?
No. The PDF is encrypted on your device and the password never leaves it.
Is anything uploaded?
No. Everything happens in your browser, on your device. Nothing you add or type is sent to this website or anywhere else.
