Drag your B2B contract or NDA here

Securely sign your B2B contracts and PDFs wherever you are in the UK

Forget the archaic, immensely time-consuming procedure of printing a commercial tenancy agreement, an NDA, or an HMRC tax form, painstakingly signing it with a black pen, scanning it with a glitchy machine, and then emailing it back. With PDFLab's advanced online signature tool, you can securely digitise the entire legal validation process directly from your web browser or smartphone.

A fluid, strictly secure, and tailor-made eSignature experience

Our advanced cloud application seamlessly turns your cursor into a precise digital pen. It explicitly allows you to trace your handwritten signature with your computer mouse, or even more naturally by using your finger (or stylus) on your smartphone's touch screen. Once fluidly created, you can position it exactly on the dotted line of your document for a visually flawless, highly professional result. Furthermore, as an unshakeable guarantee of absolute security, the biometric trace of your signature is never permanently saved or stored in our UK/EU databases once your encrypted session is closed.
