A simple Python CLI tool to generate QR codes from URLs. Supports optional logo embedding in the center of the QR code.

Features

• Generate QR codes from any URL or text
• Optional logo/image embedding in the center
• ASCII preview in terminal
• Saves as PNG file

Installation

Prerequisites

• Python 3.6 or higher

Install dependencies

pip install -r requirements.txt

Or install manually:

pip install qrcode[pil] Pillow

Usage

Basic usage

python createqrcode.py 'https://example.com' output.png

With a logo

python createqrcode.py 'https://example.com' output.png --logo logo.png

Arguments

Argument	Required	Description
url	Yes	The URL or text to encode in the QR code
output_file	Yes	The output PNG file path
--logo	No	Path to a logo image to embed in the center

Examples

Generate a simple QR code:

python createqrcode.py 'https://github.com/min-hsao' github-qr.png

Generate a QR code with your company logo:

python createqrcode.py 'https://mycompany.com' company-qr.png --logo company-logo.png

How it works

• When no logo is specified, the script uses low error correction (ERROR_CORRECT_L) for a cleaner QR code
• When a logo is added, it automatically switches to high error correction (ERROR_CORRECT_H) to ensure the QR code remains scannable
• The logo is automatically resized to 25% of the QR code size
