How to Generate Different Types of QR Codes in Laravel: A Comprehensive Guide

QR codes have become increasingly popular for their ability to encode data into a compact, easy-to-scan format. From sharing links and storing contact information to inventory management, QR codes provide versatility across a range of applications. In this blog, we’ll explore how to generate various types of QR codes in Laravel, including text-based, URL, Wi-Fi, and dynamic QR codes.

In this article we will learn how can you generate different types of QR codes on Laravel. We are going to build following QR code.

  • Simple text QR
  • Colored QR
  • Dotted QR
  • Color Gradient QR
  • Email QR
  • Phone Number QR
  • SMS QR
  • WIFI QR
  • GeoLocation QR
To generate QR we are going to use simple-qrcode package. Let's start with the integration process.

Install Simple-Qrcode package :

composer require simplesoftwareio/simple-qrcode "~4"

Create Routes :

Route::get('/QRGenerator', [QRController::class, 'show'])->name('qr.show');
Route::post('/qr-generate', [QRController::class, 'generateQR'])->name('qr.generate');

Show.blade.php - To view generated QR :

<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
    <head>
        <meta charset="utf-8">
        <meta name="viewport" content="width=device-width, initial-scale=1">
