Generate QR Code image in Python using qrcode

This Python qrcode tutorial to show you how to create a QR code image in Python using the qrcode package. Via different Python example programs we learn how to use QR code image generator library to generate QR code with simple step or custom box size, border and colors.

Install qrcode package

Installing the QR code generator package using the following command which will include pillow package for generating image.

pip install qrcode[pil]

Simple step to generate QR code in Python

In the following Python program we show you how to generate simple QR code using qrcode package to generate QR code of data ‘https://toricode.com/'

import qrcode

data = 'https://toricode.com/'
qr_image = qrcode.make(data)

qr_image.save('qrcode1.png')

Execute the program above it will generate QR code as an image named qrcode1.png as below.

Generate QR code with specified box size

The parameter box_size to specified how many pixels each box of the QR code is. By default the qrcode package define 10 as default box size.

In the following Python program we show you how to generate QR code with a given box_size with encode the same data ‘https://toricode.com/'

import qrcode

data = 'https://toricode.com/'
# generate QR code with box size 100
qr = qrcode.QRCode(box_size=100)
qr.add_data(data)

qr_image = qr.make_image()

qr_image.save('qrcode2.png')

Execute the program above it will generate QR code as an image named qrcode2.png as below which bigger than the previous QR code image.

Generate QR code with specified border

By default the qrcode package set border for output QR code image is 4. In the following Python program we generate a QR code with given border which is smaller border.

import qrcode

data = 'https://toricode.com/'
# generate QR code with border 1
qr = qrcode.QRCode(border=1)
qr.add_data(data)

qr_image = qr.make_image()

qr_image.save('qrcode3.png')

Execute the program above it will generate QR code as an image named qrcode3.png as below which bigger than the previous QR code image.

Generate QR code with specified color and background color

The qrcode package also provide API to generate QR code with given color and background color via parameter fill_color and back_color as following Python program.

import qrcode

data = 'https://toricode.com/'
qr = qrcode.QRCode()
qr.add_data(data)

# make QR code image with colors
qr_image = qr.make_image(fill_color = "blue", back_color='grey')

qr_image.save('qrcode4.png')

Execute the program above it will generate QR code as an image named qrcode4.png as below which bigger than the previous QR code image.

We also can provide color via RGB code as Python program below.

import qrcode

data = 'https://toricode.com/'
qr = qrcode.QRCode()
qr.add_data(data)

# make QR code image with colors
qr_image = qr.make_image(back_color=(255, 195, 235), fill_color=(55, 95, 35))

qr_image.save('qrcode5.png')

Execute the program above it will generate QR code as an image named qrcode5.png as below which bigger than the previous QR code image.

We also can provide colors via hexadecimal form as Python program below.

import qrcode

qr = qrcode.QRCode()
qr.add_data('https://toricode.com/')

# make QR code image with colors
qr_image = qr.make_image(back_color="#AFEEEE", fill_color="#FF1493")

qr_image.save('qrcode6.png')

Execute the program above it will generate QR code as an image named qrcode6.png as below which bigger than the previous QR code image.

Generate QR code with custom box size, border and colors

The following Python example we use three parameters above to generate QR code.

import qrcode

data = 'https://toricode.com/'
qr = qrcode.QRCode(box_size=60, border=1)
qr.add_data(data)

qr_image = qr.make_image(back_color=(255, 195, 235), fill_color=(55, 95, 35))

qr_image.save('qrcode7.png')

Execute the program above it will generate QR code as an image named qrcode7.png as below which bigger than the previous QR code image.

Happy Coding 😊
