Python QR Code Generator with Logo: A Step-by-Step Guide

Welcome to this comprehensive guide on how to generate QR codes with a custom logo using Python. In this tutorial, you will learn the step-by-step process of creating QR codes with logos, using the power of Python programming language.

Why Use QR Codes with Logos?

QR codes have become increasingly popular in recent years due to their ability to store large amounts of data in a small space. They are widely used in various industries, including marketing, retail, and event management. However, plain QR codes can sometimes lack visual appeal and fail to grab the attention of the audience. That's where QR codes with logos come in.

Getting Started

Modules Required:

To begin with, you will need to install the following Python modules:

  • qrcode
  • PIL (Python Imaging Library)

Image Used:

For this tutorial, we will use a sample logo image called 'logo.png'. You can use any image of your choice, but make sure it is in PNG format and has a transparent background.

Explanation:

Now, let's dive into the step-by-step process of generating QR codes with logos using Python:

  1. Import the required modules: import qrcode and from PIL import Image.
  2. Create a QR code instance: qr = qrcode.QRCode(version=1, error_correction=qrcode.constants.ERROR_CORRECT_L, box_size=10, border=4).
  3. Set the data to be encoded: data = 'https://www.example.com'. Replace 'https://www.example.com' with your desired URL or data.
  4. Add the data to the QR code instance: qr.add_data(data).
  5. Generate the QR code: qr.make(fit=True).
  6. Create an image from the QR code instance: img = qr.make_image(fill_color='black', back_color='white').convert('RGBA').
  7. Open the logo image: logo = Image.open('logo.png').
  8. Resize the logo image to fit the QR code: logo = logo.resize((100, 100)). Adjust the size as per your requirements.
  9. Calculate the position to place the logo on the QR code: pos = ((img.size[0] - logo.size[0]) // 2, (img.size[1] - logo.size[1]) // 2).
  10. Paste the logo image onto the QR code: img.paste(logo, pos, logo).
  11. Save the final QR code image: img.save('qrcode_with_logo.png').

Test the Code Changes

Once you have implemented the code changes, it's time to test your QR code generator with logo. Run the Python script and check if the QR code with the custom logo is generated successfully.

Customize the QR Code

If you want to customize the appearance of the QR code further, you can experiment with different colors, shapes, and design elements. The qrcode module provides various options to modify the QR code's appearance, including changing the fill color, back color, and error correction level.
