Frequently Asked Questions

Is my PDF uploaded to a server?

No. Your PDF is encrypted entirely inside your browser (Client-side). The file never leaves your computer, making it 100% private and secure.

Will this change how my PDF looks?

No, the content, layout, and text of your PDF remain exactly the same. We only add a security layer to require a password before viewing.

What if I forget the password?

Make sure you remember or save the password you set! Once encrypted, there is no way to recover or remove the password without knowing it.
