Description

The JetFormBuilder Signature addon adds a digital signature field to forms created with JetFormBuilder, allowing visitors to draw their signature directly in the browser using a mouse, finger, or touch pen. The captured image is saved along with the form submission, enabling contracts, authorizations, acceptance terms, and documents that require the sender’s manual confirmation without external steps.

Key Features

  • Native signature field: dedicated block added to the JetFormBuilder editor, dragged into any form in just a few clicks.
  • Touch or mouse capture: responsive drawing area that accepts signatures via touchscreen, trackpad, or cursor, with strokes smoothed in real time.
  • Visual customization: adjustment of stroke color, line thickness, background color, and signature area dimensions according to the form layout.
  • Signature storage: the signature is recorded as an image attached to the submission, available in the submissions list for later reference.
  • Clear button: integrated control allowing the user to erase the stroke and redo the signature before confirming submission.

Benefits of JetFormBuilder Signature

  • Documents with valid acceptance: collects the user’s handwritten confirmation without relying on external signature platforms.
  • Frictionless submission flow: the visitor signs and submits on the same screen, reducing abandonment in long forms.
  • Mobile compatibility: works on phones and tablets, expanding the reach of digital contracts and terms.
  • Auditable record: maintains the submission history with the signature image linked to each submission.

Who Is It For?

  • Sites that need to collect acceptance terms, authorizations, or digital contracts directly in forms.
  • Clinics, schools, and service providers that use JetFormBuilder for registration forms with customer confirmation.
  • Agencies and developers delivering projects on Crocoblock who need to add signature capture without relying on third-party services.

The addon addresses a recurring requirement in acceptance, authorization, and service provision forms: recording the user’s consent with a handwritten signature. Combined with the rest of the JetFormBuilder ecosystem, it completes the data collection cycle with visual confirmation stored alongside the submission, without redirecting visitors to external tools or disrupting the completion flow.
