Question 1

How secure is it?

Accepted Answer

It uses 256-bit AES encryption, the current standard for PDFs. Without the password, the content cannot be read. Use a long password that is hard to guess.

Question 2

What if I forget the password?

Accepted Answer

There is no way to recover it: not even we know it, because everything happens in your browser. Keep it somewhere safe.

Question 3

Can I remove the password later?

Accepted Answer

Yes, with the "Unlock PDF" tool, by typing the password.

Question 4

Is it free?

Accepted Answer

Yes. All LeuPaPDF tools are free and you do not need to sign up.

Question 5

Are my files uploaded to a server?

Accepted Answer

No. The file is processed inside your browser, on your device. Nobody else can see it and it is gone when you close the tab.
