Frequently asked questions
Are my files uploaded to a server?
No. Everything happens in your browser: your documents never leave your device and nobody else can see them.
Is it secure?
Yes. It uses 256-bit AES encryption, the same standard as Adobe Acrobat. A long password is practically impossible to guess.
What if I forget the password?
It can't be recovered. Keep an unprotected copy of the original PDF too.
