How to Build a QR Code Generator in Django (Step-by-Step Guide)

QR Codes are widely used for payments, marketing campaigns, WiFi sharing, and WhatsApp links.

In this tutorial, we’ll build a simple QR Code generator using Django and Python.

---

Step 1 — Install the Required Library

Install the qrcode package:

pip install qrcode[pil]

---

Step 2 — Create the View

Inside your Django app, create a view:

import qrcode
from django.http import HttpResponse
from io import BytesIO

def generate_qr(request):
    data = request.GET.get("data", "Hello World")

    qr = qrcode.make(data)
    buffer = BytesIO()
    qr.save(buffer, format="PNG")

    return HttpResponse(buffer.getvalue(), content_type="image/png")

Now you can access:

http://localhost:8000/generate_qr/?data=Hello

And the QR code will be generated dynamically.

Step 3 — Configure URLs

In urls.py:

from django.urls import path
from .views import generate_qr

urlpatterns = [
    path("generate_qr/", generate_qr),
]

---

Step 4 — Extending the Generator

You can extend this project to support:

• WiFi QR Codes
• WhatsApp QR Codes
• Email QR Codes
• vCard contact QR Codes
• Custom colors
• Logo inside QR

For example, generating a WhatsApp QR:

data = f"https://wa.me/{phone_number}"

Production Considerations

• Add caching for performance
• Implement rate limiting
• Optimize SEO for each QR type
• Add multilingual support
• Create a frontend interface
