Get a Windows installer from https://www.imagemagick.org/script/download.php down towards the bottom of the page.

It is command line. The command to split into 4 is

Code:

magick map.png -crop 2x2@ out_%02d.png

For comparison: The map.png 22000x22000 px is 307 MB on disk
took 2'30" to split into 4 11000x11000 px png's  and a lot of cpu activity.
