How strong is the protection?
Plooi encrypts with AES-256, the PDF 2.0 standard. How strong it is depends mostly on your password: choose a long sentence rather than a short word.

What if I forget the password?
Then nobody can open the PDF any more, not even Plooi. Keep your password safe, or keep the original without a password.

Can anyone see my password?
No. Your password and your PDF stay in your browser. Nothing goes to a server.
