Does FormNX support eSignatures?
Yes. FormNX includes a Signature Field element in the form builder. Add it to your form and respondents can sign directly in the browser with a mouse, finger, or stylus — no printing, scanning, or emailing PDFs back and forth.
The Signature field is available on every plan, including Free.

What gets recorded when someone signs
A signature on its own is just an image. What makes it useful later is the record stored alongside it.
Recorded automatically with every signed submission
| What's stored | Where to find it |
|---|---|
| The signature image the respondent drew | With the submission, in View Responses |
| The signer's IP address (including location and network details) | Visitor Info |
| The browser and operating system used to sign | Visitor Info |
| A visitor ID identifying the user who submitted | Visitor Info |
| The date and time the submission was received | With the submission |
You don't need to switch any of these on — they're captured for every submission.
Available, but you need to set them up first
Two things people often assume are automatic are not. Both are worth enabling for agreements and contracts:
- A unique reference number for each signed document. Turn on Submission Reference Number Generation under Settings → Form Submission Reference. You can set your own prefix, suffix and starting number, so every signed agreement gets a traceable ID like
AGR-1042. - A PDF copy of the completed document, emailed on signing. This takes two steps: first create a PDF for the form, then attach that PDF to your notification and responder emails. Once set up, you and the signer each receive an independent, timestamped copy of what was signed — in practice the single most useful thing to have if the terms are ever questioned later.
Signature field (Is Required on) + Submission Reference Number + PDF attached to email. Mark the Signature field as Sensitive Data so it's handled with extra care in submissions.
Controlling who can sign
For agreements meant for one specific person rather than anyone with the link:
- Password protect the form so it can't be opened by anyone who simply comes across the link.
- Add email verification (OTP) for an extra layer on higher-value agreements.
- Use a close date or response limit to stop accepting signatures after a deadline, or once the document has been signed.
A note on validity
FormNX signatures are electronic signatures of the kind usually described as a "simple electronic signature" — the same broad category most e-sign tools operate in, and the category frameworks such as the US ESIGN Act and EU eIDAS refer to. The supporting record described above (signature image, IP address, browser and device, timestamp, and optionally a reference number and a PDF copy held by both parties) is the evidence that backs up a signature if it's ever questioned.
Whether an electronic signature is appropriate depends on your document type and your country — some categories of document are excluded from e-signing in some jurisdictions. This page is general information, not legal advice; if you're signing something high-value or regulated, please confirm the requirements for your own situation.
