Frequently Asked Questions

Is an electronic signature like this legally valid?

In many countries, including under the US ESIGN Act and the EU eIDAS regulation, a drawn electronic signature is legally recognised for most everyday agreements. High-value or regulated documents may require a cryptographic digital signature with a certificate, which is a different mechanism. Check the requirements that apply to your document.

Can I sign on more than one page?

Sign and download the document, then add the signed file back and repeat for the next page. Each pass places one signature.

Is my contract uploaded anywhere?

No. This tool runs entirely inside your browser using WebAssembly — your file is never uploaded, never stored on a server, and never seen by us. You can confirm it by opening your browser's Network tab while the tool runs, or by disconnecting from the internet after the page loads: it still works.
