Frequently asked questions
How secure is the protection?
The PDF is encrypted with AES-256, the strongest method PDF supports. How secure it is depends on the password: use 12 characters or more, for example a memorable sentence.
I forgot the password.
Then the PDF can no longer be opened. We store neither the file nor the password and cannot help. Keep an unprotected copy of the original.
