How do I save a QR code as an image in Python?

With the qrcode library, use qrcode.make("data").save("qr.png"). For more control, use qrcode.QRCode() and call make_image() with fill_color and back_color parameters.

Can Python generate QR codes without Pillow?

Yes. The segno library generates SVG and terminal output without Pillow. The qrcode library can also output to the terminal or generate SVG without Pillow installed.

How do I add a logo to a QR code in Python?

Generate the QR code with high error correction (ERROR_CORRECT_H), then use Pillow to paste a logo in the center. Or use the QRCode.fun API which handles logo placement automatically.

Can I generate QR codes in a Django application?

Yes. Install the qrcode package, generate QR codes in your views or management commands, and serve them as images or base64 data URLs in templates.

Generate QR Codes with Python Libraries

Code examples using popular Python QR code libraries.

Basic QR Code with qrcode

import qrcode

# Simple generation
img = qrcode.make('https://qrcode.fun')
img.save('qrcode.png')

# Advanced with customization
qr = qrcode.QRCode(
    version=1,
    error_correction=qrcode.constants.ERROR_CORRECT_H,
    box_size=10,
    border=4,
)
qr.add_data('https://qrcode.fun')
qr.make(fit=True)

img = qr.make_image(fill_color='#1A2B3C', back_color='white')
img.save('qrcode_custom.png')

SVG Output with segno

import segno

qr = segno.make('https://qrcode.fun')
qr.save('qrcode.svg', scale=10)
qr.save('qrcode.png', scale=10, dark='#1A2B3C')

QR Code with Logo

import qrcode
from PIL import Image

qr = qrcode.QRCode(error_correction=qrcode.constants.ERROR_CORRECT_H)
qr.add_data('https://qrcode.fun')
qr.make(fit=True)

img = qr.make_image(fill_color='#1A2B3C', back_color='white').convert('RGB')

# Add logo
logo = Image.open('logo.png')
logo_size = img.size[0] // 4
logo = logo.resize((logo_size, logo_size))

pos = ((img.size[0] - logo_size) // 2, (img.size[1] - logo_size) // 2)
img.paste(logo, pos)
img.save('qrcode_logo.png')

QRCode.fun API

Generate QR Codes via API in Python

Call the QRCode.fun API from Python to generate styled QR codes with custom colors, shapes, and logos.

Python API Integration

import requests

response = requests.post('https://qrcode.fun/api/generate-qr-styled', json={
    'data': 'https://qrcode.fun',
    'width': 300,
    'height': 300,
    'type': 'png',
    'margin': 10,
    'dotsOptions': {
        'color': '#1A2B3C',
        'type': 'rounded'
    },
    'cornersSquareOptions': {
        'color': '#8564C3',
        'type': 'extra-rounded'
    },
    'backgroundOptions': {
        'color': '#FFFFFF'
    }
})

result = response.json()
# result['data'] contains the base64 PNG data URL
print(result['data'][:50])
