Source Code
I chose Python and OpenCV for image converting functions.
Install Python3 for your OS, and install OpenCV from pip.
pip install opencv-python
This is the script I wrote.
It reads ".JPG" files in source directory and outputs converted files to destination directory.
Gallery
Here are some images I've made.
