Frequently asked questions
How secure is the encryption?
We use AES-256, the strongest standard encryption supported by PDF. With a strong password, the file can't realistically be opened without it.
What if I forget the password?
We never see or store your password, so it can't be recovered. Keep a copy of the original file or store the password somewhere safe.
Will it open in any PDF reader?
Yes. AES-256 is supported by Adobe Acrobat, Chrome, Edge, Firefox, macOS Preview and all modern PDF readers.
