Depends on the software you play from. Usually it will get just scaled down to fit (losing quality of course)

The image gets shrunk. There are several ways of doing that. You could just skip pixels.

So for instance, a line from the image with 8 pixels:

12345678

when shrunk by half would become:

1357

You don’t need to do it by halves, for instance you could do by a third by removing every third pixel:

124578

But that doesn’t give the best results, because it looks really bad on fine details. Like if there’s a single pixel thick line somewhere it can just vanish entirely when you do things that way.

So a better way to do that is to average the pixels. If you have a black line surrounded by white and shrink that you get a middle grey sort of line.
