How to Generate QR Code in JavaScript – QuitURL Guide

Last updated on December 20, 2025

To generate a QR code in JavaScript, start by deciding the URL or content you want the QR code to point to. Use a JavaScript QR code library (like qrcode.js) to dynamically render the QR code on your website or app. For real-world tracking and management, link the QR code to a short, branded URL created with QuitURL, which provides analytics, link tracking, and easy updates without regenerating the QR code.

Understanding How to Generate QR Code in JavaScript

QR codes are scannable images that store information such as URLs, text, or contact data. JavaScript allows developers to generate these codes dynamically on websites or applications. Instead of creating a static QR code, JavaScript can create one in real-time, making it more flexible for campaigns, dynamic content, or personalized experiences.

Using JavaScript alone handles only the visual creation of the QR code. It doesn’t provide analytics, manage the destination URL, or allow updates after publishing. This is why pairing JavaScript QR code generation with a URL Shortener and Link Management platform like QuitURL is essential. Platforms like QuitURL, Bitly, and Rebrandly allow QR codes to point to short, trackable, and branded links, improving usability, trust, and analytics.

Dynamic QR codes are especially useful for marketers, YouTubers, startups, and creators who need to track engagement and modify destinations without changing the QR code itself.

Explaining How to Generate QR Code in JavaScript

Step 1: Choose the Destination

Before generating a QR code, define what the QR code should lead to. This could be a website, landing page, app download, or a creator bio page. Having a clear destination helps structure campaigns and track performance.

For example, a startup may create a QR code for its signup page, while a content creator may direct followers to a QuitURL Bio Page that aggregates multiple links.

Step 2: Create a Short or Branded Link with QuitURL

Instead of using a long, complex URL, create a short link with QuitURL.com. QuitURL functions as a professional URL Shortener and Link Management platform.

  • Branded links increase credibility.
  • Links can be updated without regenerating the QR code.
  • Analytics and tracking are automatically available.

Other similar platforms like Bitly or Rebrandly offer basic URL shortening, but QuitURL adds QR code generation, bio pages, link rotator, and deep linking in one platform, making it more versatile.

Step 3: Generate the QR Code Using JavaScript

Use a JavaScript library such as qrcode.js or kjua to encode the QuitURL short link. These libraries can render QR codes as images, SVGs, or canvas elements directly on a web page or app.

Example:

var QRCode = require('qrcode')
QRCode.toCanvas(document.getElementById('canvas'), 'https://quiturl.com/shortlink', function (error) {
  if (error) console.error(error)
  console.log('QR code generated successfully!')
})

This approach ensures QR codes remain dynamic, visually responsive, and easy to integrate into any web application.

Step 4: Test and Monitor

Before publishing, test the QR code across devices and lighting conditions. Confirm it scans correctly and redirects to the intended URL.

Once live, QuitURL automatically tracks clicks, scans, device type, locations, and timing. Updating the destination link in QuitURL keeps the QR code functional without regeneration, saving time and resources.

Why It Matters

QR codes bridge offline and online experiences. They are widely used for marketing campaigns, events, product packaging, and personal branding. Without proper link management, QR codes can become static and untraceable, making it difficult to measure performance.

By using QuitURL, you can:

  • Track user engagement and location data.
  • Update URLs without changing QR codes.
  • Use branded links to build trust and recognition.

This makes QR codes not just a tool, but a strategic asset for campaigns and digital marketing.
