QR codes are everywhere—from product packaging to payment apps—and building your own Python QR Code Generator with Tkinter is one of the most practical and beginner-friendly programming projects. Whether you’re a student, hobbyist, or developer looking to expand your desktop development skills, this guide will walk you through building a complete app using just Python and Tkinter.
Let’s build something simple, elegant, and useful—no web hosting required.

Why Choose Python and Tkinter for QR Code Generation?
Python is praised for its simplicity and readability, making it an ideal choice for rapid application development. When paired with Tkinter, the default GUI package for Python, you can easily build cross-platform desktop interfaces.
Creating a QR code generator using Python and Tkinter gives you:
- Full control over input and output.
- Offline functionality without relying on online QR generators.
- The ability to integrate features such as saving images or customizing QR styles.
If you’re new to Python GUI development, this project is an excellent stepping stone.
Requirements and Initial Setup
To follow this tutorial, make sure you have:
- Python 3.x installed (download from python.org)
- Pillow for image handling
- The
qrcode
library
Install the required libraries via pip:
bashCopiarEditarpip install qrcode[pil]
Tkinter is included in standard Python installations, so no additional steps are required for that.
Building the QR Code Generator GUI
Below is a simple example that demonstrates how to build a QR code generator in Python using Tkinter:
pythonCopiarEditarimport qrcode
import tkinter as tk
from PIL import Image, ImageTk
def generate_qr():
data = entry.get()
if data:
qr = qrcode.make(data)
qr.save("qr_output.png")
img = Image.open("qr_output.png")
img = ImageTk.PhotoImage(img)
qr_label.config(image=img)
qr_label.image = img
root = tk.Tk()
root.title("QR Code Generator")
entry = tk.Entry(root, width=40)
entry.pack(pady=10)
generate_btn = tk.Button(root, text="Generate QR Code", command=generate_qr)
generate_btn.pack()
qr_label = tk.Label(root)
qr_label.pack()
root.mainloop()
In just a few lines, you have a complete app that takes user input, generates a QR code, and displays it inside the app window.
Add More Functionality
Once the basic version works, you can add features like:
- Choosing where to save the image
- Setting custom QR code colors
- Reading QR codes using the
pyzbar
oropencv-python
libraries - Adding error correction levels (L, M, Q, H)
Real-World Applications for Your QR Code App
This tool isn’t just a fun project—it can solve real problems:
- Educators can create QR codes for classroom materials.
- Small business owners can generate codes for product labels, menus, or contact details.
- Web developers can create complementary tools like WiFi QR Code Generators.

How This Project Compares to Other JavaScript-Based QR Tools
While browser-based tools like the URL Shortener App or the Focus Timer App offer convenience, desktop apps are ideal when you need:
- Offline access
- Customizability
- Higher data privacy
Combining both desktop and web tools can significantly expand your developer toolkit.
