Frequently asked questions
Is my document uploaded to sign it?
No. Your signature is drawn onto the PDF in your browser with pdf-lib, so the document never leaves your device.
How do I make my signature?
Three ways: draw it with your mouse or finger, type your name in a handwriting-style font, or upload an image of your signature (a transparent PNG works best).
Is this a legally binding signature?
It adds a visible electronic signature, which is widely accepted for everyday agreements. It is not a cryptographic digital signature, so for high-assurance or regulated use you may need a dedicated e-signature service.
