Digital Signature For Gravity Forms

Digital Signature For Gravity Forms is a free WordPress plugin that adds a fully interactive, handwritten digital signature field to any Gravity Forms form. Let clients, customers, employees, or users draw their signature directly in the browser — on desktop or mobile — and capture it as a permanent part of the Gravity Forms submission.

Whether you are collecting client consent, service agreement sign-offs, legal acknowledgments, employee authorizations, medical intake approvals, or event waivers, this plugin brings professional e-signature capability directly into Gravity Forms — with no third-party signature service, no per-signature fees, and no complicated setup required.

Requires Gravity Forms to be installed and activated on your WordPress site.

Why Use Digital Signature For Gravity Forms?

Gravity Forms does not include a native signature field. This plugin fills that gap cleanly — adding a smooth, touch-friendly HTML5 canvas signature pad that works just like any other Gravity Forms field. It is the simplest way to capture meaningful, handwritten e-signatures as part of any form submission workflow in WordPress.

Unlike third-party e-signature services, everything stays inside your own WordPress installation. Signatures are saved directly to Gravity Forms entries, visible in the admin dashboard, and can be included in email notifications — all in the free version.

Free Features

• ✅ Clear / Reset Button — A dedicated button lets users erase and redraw their signature before submitting
• ✅ Custom Note / Instruction Text — Add a custom instructional notice message below the signature pad to guide users on what to sign or agree to
• ✅ Required Field Support — Mark the signature field as required so the form cannot be submitted without a drawn signature

• ✅ Merge Tag Support — Reference the signature value using a merge tag in Gravity Forms email and notification fields
• ✅ Conditional Logic Support — The signature field works with Gravity Forms conditional logic, allowing it to show or hide based on other field values
• ✅ Native GF Field Integration — Registers as a proper Gravity Forms field type in the Advanced Fields section — drag, drop, and configure like any standard field

How It Works

1. Install and activate the plugin (Gravity Forms must already be active).
2. Open any Gravity Forms form in the form editor.
3. Find the Digital Signature field in the Advanced Fields panel and drag it into your form.
4. In the field settings, configure the pad background color, pen color, pen stroke width, note text, required setting, and validation message.
5. Save the form and embed it on any page or post.
6. Visitors can now draw their signature on the canvas using a mouse, trackpad, finger, or stylus — and clear and redo it as needed before submitting.
