Embed

Embedding places QR code images or interactive widgets into web pages, emails, applications, and documents. Just as QR codes are printed on physical materials, there are many scenarios where they need to appear in digital content - event registration confirmations, e-commerce order pages, digital business cards, and marketing emails.

The simplest embedding method uses an HTML <img> tag with a QR code generation APIURL as the src attribute. When the page loads, the QR code generates dynamically without needing to upload image files to a server. Changing URL parameters produces different QR codes, making this approach highly flexible for dynamic content.

Email embedding delivers personalized QR codes to each recipient. By including a recipient ID as a parameter in the QR generation API URL within an email template, a unique QR code displays when the email is opened. This enables individual tracking of event check-ins, coupon redemptions, and loyalty program interactions - all tied to specific recipients.

JavaScript libraries enable real-time browser-side QR code generation. When a user types a URL into a form, a QR code appears instantly on screen. No server communication is required, making this approach fast and privacy-friendly. Libraries like qrcode.js and node-qrcode render QR codes as Canvas elements or SVG, giving developers full control over styling and integration with surrounding page elements.
