[Solved] How to determine the utm zone in a world file

jlcv Asks: How to determine the utm zone in a world file
According to this page the utm zone is ambiguous. If so, how come when I load it in some GIS software it seems to know where the image is located on earth? How do I determine the utm zone in a world file? I want to create a world file for my image and I have the gps coordinates of the corners of my image file. But I am not sure how to convert that to UTM values pertaining to the world file format.

To give a bit more context I am trying to create this world file so that I can georeference images on JOSM and annotate on top of it.
