Is an Electronic Signature Legally Binding?
Yes — in most jurisdictions. In the United States, the ESIGN Act (2000) and UETA make electronic signatures legally equivalent to handwritten ones for the vast majority of contracts and documents. In the EU, eIDAS regulation covers electronic signatures. In Canada, PIPEDA and provincial e-commerce acts apply. Exceptions include wills, adoption papers, and certain government documents that still require wet ink signatures. For any high-stakes legal document, confirm requirements with a lawyer.
Draw vs Type vs Upload — Which Signature Method to Use?
Drawing your signature with a mouse or trackpad produces the most natural result but requires a steady hand. Typing your name in a cursive font is fastest and looks professional for most business documents. Uploading a scanned signature image looks exactly like your handwritten signature — use a white piece of paper, sign with a dark pen, photograph it in good light, then use an image background remover to make it transparent before uploading. For daily use, the typed method is fastest; for important contracts, the drawn or uploaded image method is most convincing.
