Usage

usage.tsx
import { Dice4 } from "lucide-react";import {  QRCode,  QRCodeCanvas,  QRCodeOverlay,  QRCodeSkeleton,} from "@/registry/bases/radix/ui/qr-code";export default function QRCodeWithLogo() {  return (    <QRCode value="https://diceui.com" size={120} level="H" className="gap-4">      <QRCodeSkeleton />      <QRCodeCanvas />      <QRCodeOverlay className="rounded-full border-2 border-white p-2">        <Dice4 className="size-6" />      </QRCodeOverlay>    </QRCode>  );}
  • Compare canvas, SVG, and image QR-code renderings with the same value and overlay.
  • Show a logo or icon centered on a QR code.
  • Demonstrate how high error correction can be used when placing content over a QR code.
  • Use as a starting point for displaying a QR code alongside a clear text alternative or destination link.

Examples

Canvas with logo

Render the QR code on canvas and place a Dice icon over its center.

canvas-with-logo.tsx
import { Dice4 } from "lucide-react";import {  QRCode,  QRCodeCanvas,  QRCodeOverlay,  QRCodeSkeleton,} from "@/registry/bases/radix/ui/qr-code";export default function CanvasWithLogo() {  return (    <QRCode value="https://diceui.com" size={120} level="H" className="gap-4">      <QRCodeSkeleton />      <QRCodeCanvas />      <QRCodeOverlay className="rounded-full border-2 border-white p-2">        <Dice4 className="size-6" />      </QRCodeOverlay>    </QRCode>  );}

SVG with logo

Render the QR code as SVG and give the centered icon badge an accent-to-muted gradient.

svg-with-logo.tsx
import { Dice4 } from "lucide-react";import {  QRCode,  QRCodeOverlay,  QRCodeSkeleton,  QRCodeSvg,} from "@/registry/bases/radix/ui/qr-code";export default function SvgWithLogo() {  return (    <QRCode value="https://diceui.com" size={120} level="H" className="gap-4">      <QRCodeSkeleton />      <QRCodeSvg />      <QRCodeOverlay className="rounded-full border-2 border-white bg-linear-to-br from-accent to-muted p-2">        <Dice4 className="size-6" />      </QRCodeOverlay>    </QRCode>  );}

Image with logo

Render the QR code as an image with a smaller centered logo badge.

image-with-logo.tsx
import { Dice4 } from "lucide-react";import {  QRCode,  QRCodeImage,  QRCodeOverlay,  QRCodeSkeleton,} from "@/registry/bases/radix/ui/qr-code";export default function ImageWithLogo() {  return (    <QRCode value="https://diceui.com" size={120} level="H" className="gap-4">      <QRCodeSkeleton />      <QRCodeImage />      <QRCodeOverlay className="rounded-full border-2 border-white p-1.5">        <Dice4 className="size-6" />      </QRCodeOverlay>    </QRCode>  );}

Accessibility

  • The demo does not specify an accessible name or text alternative for the QR code; provide a nearby description or destination link so users are not required to scan it.
  • Do not rely on the overlaid Dice icon to communicate the QR code’s destination or purpose.
  • Check that the overlaid badge does not prevent reliable scanning; the demo sets the QR code error-correction level to H.
