Create Stunning Custom QR Codes with Python’s MyQR Library

This article teaches how to use the Python third‑party library myqr to generate various QR codes, including ordinary, artistic, and animated styles.

QR Code Types

Ordinary QR code

Artistic QR code (image‑embedded)

Animated QR code (GIF)

1. Install myqr

Ensure Python 3.x is installed, then run: pip install myqr Successful installation will display a confirmation message.

2. Basic Usage

myqr runs from the command line. The basic syntax is: myqr <span>URL</span> For example: myqr https://zhuanlan.zhihu.com/pydatalysis This creates a QR code image for the given URL in the current directory.

3. Ordinary QR Code

Generate a standard QR code with the default command shown above.

Adjust the size with -v (range 1‑40):

myqr https://zhuanlan.zhihu.com/pydatalysis -v 10

Rename the output file with -n:

myqr https://zhuanlan.zhihu.com/pydatalysis -v 10 -n pydatas.jpg

Specify a save directory with -d:

myqr https://zhuanlan.zhihu.com/pydatalysis -v 10 -n pydatas.jpg -d c:\picture\

4. Artistic QR Code

Embed a static image into the QR code using -p followed by the image path:

myqr https://zhuanlan.zhihu.com/pydatalysis -p d:\hmbb.jpg

Make the QR code colorful by adding the -c flag:

myqr https://zhuanlan.zhihu.com/pydatalysis -p d:\hmbb.jpg -c

Fine‑tune visual appearance with contrast ( -con) and brightness ( -bri) parameters, where the default value is 1.0.

5. Animated QR Code

Use a GIF image as the overlay (via -p) to produce an animated QR code; the output will also be a GIF.

All other parameters (size, naming, directory, color, contrast, brightness) work the same as for ordinary and artistic QR codes.
