Frequently asked questions
What kind of protection is this?
The PDF is encrypted with a password. Anyone who wants to open it will need to type that exact password.
Is the password sent anywhere?
No. The encryption happens entirely in your browser. Neither your file nor your password is ever uploaded.
What if I forget the password?
There is no way to recover it. Keep it somewhere safe, because without it the PDF cannot be opened.
Does it add a watermark?
No. The protected PDF is clean, only encrypted.
