Frequently asked questions
Is my password sent anywhere?
No. Encryption runs entirely in your browser, and your password is never stored or logged. Nothing is sent to any server.
What if I forget my password?
It can't be recovered, because nothing is stored outside your file. Save your password somewhere safe before you download the protected PDF.
What do the permission restrictions do?
They can stop printing, copying text, or editing. Restrictions are enforced by PDF readers that respect them, and they use a separate owner password, so they can't be removed with the password you set.
