It's a small python script, written in python3 by which one can convert JPG format images to PNG format.
The script takes two folder names.The first folder will be full of jpg images that you will give and the second folder will be created by the script.
python3 jpgTOpngConver.py image_folder\ output_folder\
python3 jpgTOpngConver.py image_folder/ output_folder/
python3 jpgTOpngConver.py image_folder/ output_folder/
NB:Don't forget those slashes
