Frequently Asked Questions (FAQ)
Q: What happens if I forget the password?
A: Because of our high-security, zero-knowledge policy, there is absolutely no way for us to recover a forgotten password. The encryption is irreversible without it. Please be sure to store your password in a safe place.
Q: Can someone just crack the password?
A: It is computationally infeasible to break strong AES encryption with modern technology. The security of your document relies on the strength of your password. A short, simple password can be guessed, but a long, complex one provides robust security.

A: Yes. If you need to remove the password, you can use our Unlock PDF tool, but you will need to provide the correct, original password to do so.
