Signature Pad

A component that allows users to draw a signature using a signature pad.

Signature

Anatomy

To set up the signature pad correctly, you'll need to understand its anatomy and how we name its parts.

Each part includes a data-part attribute to help identify them in the DOM.

Examples

Learn how to use the Signature Pad component in your project. Let's take a look at the most basic example:

import { SignaturePad } from '@ark-ui/react'

export const Basic = () => (
  <SignaturePad.Root>
    <SignaturePad.Label>Sign below</SignaturePad.Label>
    <SignaturePad.Control>
      <SignaturePad.Segment />
      <SignaturePad.ClearTrigger>Clear</SignaturePad.ClearTrigger>
      <SignaturePad.Guide />
    </SignaturePad.Control>
  </SignaturePad.Root>
)

import { SignaturePad } from '@ark-ui/solid'

export const Basic = () => (
  <SignaturePad.Root>
    <SignaturePad.Label>Sign below</SignaturePad.Label>
    <SignaturePad.Control>
      <SignaturePad.Segment />
      <SignaturePad.ClearTrigger>Clear</SignaturePad.ClearTrigger>
      <SignaturePad.Guide />
    </SignaturePad.Control>
  </SignaturePad.Root>
)

<script setup lang="ts">
import { SignaturePad } from '@ark-ui/vue'
</script>

<template>
  <SignaturePad.Root>
    <SignaturePad.Label>Sign below</SignaturePad.Label>
    <SignaturePad.Control>
      <SignaturePad.Segment />
      <SignaturePad.ClearTrigger>Clear</SignaturePad.ClearTrigger>
      <SignaturePad.Guide />
    </SignaturePad.Control>
  </SignaturePad.Root>
</template>

Image Preview

After the user draws a signature, you can display a preview of the signature as an image. This is useful when you want to show the user a preview of the signature before saving it.

import { useState } from 'react'
import { SignaturePad } from '@ark-ui/react'

export const ImagePreview = () => {
  const [imageUrl, setImageUrl] = useState('')

  return (
    <>
      <SignaturePad.Root
        onDrawEnd={(details) => details.getDataUrl('image/png').then((url) => setImageUrl(url))}
      >
        <SignaturePad.Label>Sign below</SignaturePad.Label>
        <SignaturePad.Control>
          <SignaturePad.Segment fill="orange" />
          <SignaturePad.ClearTrigger>Clear</SignaturePad.ClearTrigger>
          <SignaturePad.Guide />
        </SignaturePad.Control>
      </SignaturePad.Root>

      {imageUrl && <img src={imageUrl} alt="Signature" />}
    </>
  )
}

import { Show, createSignal } from 'solid-js'
import { SignaturePad } from '@ark-ui/solid'

export const ImagePreview = () => {
  const [imageUrl, setImageUrl] = createSignal<string>()

  return (
    <>
      <SignaturePad.Root
        onDrawEnd={(details) => details.getDataUrl('image/png').then((url) => setImageUrl(url))}
      >
        <SignaturePad.Label>Sign below</SignaturePad.Label>
        <SignaturePad.Control>
          <SignaturePad.Segment fill="orange" />
          <SignaturePad.ClearTrigger>Clear</SignaturePad.ClearTrigger>
          <SignaturePad.Guide />
        </SignaturePad.Control>
      </SignaturePad.Root>
      <Show when={imageUrl()}>
        <img src={imageUrl()} alt="Signature" />
      </Show>
    </>
  )
}

<script setup lang="ts">
import { ref } from 'vue'
import { SignaturePad, type SignaturePadDrawEndDetails } from '@ark-ui/vue'

const imageUrl = ref<string | null>(null)

const handleDrawEnd = async (details: SignaturePadDrawEndDetails) => {
  imageUrl.value = await details.getDataUrl('image/png')
}
</script>

<template>
  <SignaturePad.Root @draw-end="handleDrawEnd">
    <SignaturePad.Label>Sign below</SignaturePad.Label>
    <SignaturePad.Control>
      <SignaturePad.Segment fill="orange" />
      <SignaturePad.ClearTrigger>Clear</SignaturePad.ClearTrigger>
      <SignaturePad.Guide />
    </SignaturePad.Control>
  </SignaturePad.Root>
  <img v-if="imageUrl" :src="imageUrl" alt="Signature preview" />
</template>
