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

• ✅ Interactive Signature Pad — A smooth HTML5 canvas-based drawing area lets users sign directly in the browser using a mouse, trackpad, finger, or stylus
• ✅ Touch & Mobile Support — Fully touch-compatible with native touch event handling for smooth, natural signing on smartphones and tablets
• ✅ Custom Pad Background Color — Set the background color of the signature canvas to match your form or brand design
• ✅ Custom Pen / Ink Color — Choose the color of the signature stroke to produce black, blue, or any custom ink appearance
• ✅ Adjustable Pen Stroke Width — Control the thickness of the signature pen for a natural, handwritten feel; configurable directly from the field settings
• ✅ 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
• ✅ Custom Validation Error Message — Define your own error message that displays when the required signature field is left empty on submission
• ✅ Signature Saved to Entry — The captured signature is saved as an image file and displayed directly in the Gravity Forms entry viewer in the WordPress admin

• ✅ 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
• ✅ Velocity-Based Stroke Width — Stroke thickness dynamically varies based on drawing speed, replicating the natural feel of pen on paper
