FAQ

How do I password-protect a PDF?
Import the PDF, type the password twice, tick “Confirm password”, then run protection. Download starts automatically when encryption finishes.
Is my PDF encrypted on your servers?
No. Everything runs locally in the browser using a PDF library that supports standard document encryption.
What encryption level is used?
PDF standard security (typically described as AES-128 or AES-256 depending on the PDF version). Flownect never stores your password.
How do I open a protected PDF?
In any recent PDF viewer: enter the user password when prompted. Without it, the document cannot be read.
