Features

This application is packed with features to give you complete creative control:

🎨 Advanced Logo Integration

• Upload Any Logo: Easily upload your brand's logo (PNG, JPG, JPEG).
• Multiple Logo Shapes: Mask your logo into a Square, Circle, or a modern Rounded Rectangle.
• Professional Background Styles:
  • Solid: A clean, solid-colored frame behind the logo.
  • Gradient Halo: A stunning effect where the QR code modules smoothly fade out as they approach the logo, creating a soft, professional clearing.
  • Radial Gradient: A vibrant circular gradient behind the logo for an eye-catching effect.
• Logo Border: Add a crisp border around the logo that intelligently adapts to the chosen shape.

⚙️ Full QR Code Control

• Error Correction Level (ECL): Choose from Low, Medium, Quartile, or High levels. The app provides a warning if you use a logo without High ECL.
• Version (Size) Control: Specify the exact minimum and maximum QR code version to use.
• Mask Pattern Selection: Let the library auto-select the optimal mask for readability, or manually force one of the 8 patterns.
• Boost ECC: Automatically increase the error correction level if it can be done without increasing the QR version, making your code more robust for free.

🖌️ Styling and High-Resolution Output

• Full Color Control: Use color pickers to choose exact hex colors for both the QR code and its background.
• Adjustable Module Size: Control the pixel size of each square in the QR code, allowing you to generate high-resolution PNGs perfect for print and digital media.
• Customizable Quiet Zone: Adjust the width of the border (quiet zone) around the QR code.
• Download as PNG: Save your final creation as a high-quality PNG file with a single click.

Setup and Installation

Follow these steps to get the application running on your local machine.

Prerequisites

• Python 3.8 or newer
• pip (Python's package installer)

1. Get the Code

Download the project files and place them in a single project folder. Your folder should contain:

• qr_code_app.py
• qrcodegen.py
• requirements.txt

2. Create a Virtual Environment (Recommended)

It is highly recommended to use a virtual environment to keep project dependencies isolated.

Open your terminal or command prompt and navigate to the project directory:

# Create a virtual environment named '.venv'
python -m venv .venv
