Questions answered
Sign PDF FAQ
Is my PDF uploaded when I sign it?
No. The signature is drawn on your device and added to the PDF with browser-side JavaScript, so the document is never uploaded or stored on a server.
Can I draw, type, or upload a signature?
Yes. You can draw a signature with your mouse or finger, type your name in a handwriting-style font, or upload an image of your signature. You can also save initials and add text, date, and checkbox fields.
Is this a legally binding digital signature?
This tool adds a visible signature image to the PDF. It is not a cryptographic digital certificate. For certificate-based e-signatures, use a dedicated e-signature service.
