ImageMagick does support displaying images but it only supported when you use x11 (Xwayland).

# the `display` command will give you a missing error even if you have ImageMagick installed (At least on my winget installation of ImageMagick)
display image.png
# give you a x11 error on windows
magick display image.png

if for some reason you want something similar you could use ffplay it both supported on windows and x11 from what I know.

I tried it for batch conversion and I was very disappointed it somehow skipped files on big batches

I haven't had any issues with ImageMagick with converting images, but I would rather use a dedicate command for encoder like avifenc, cjxl, cjpegli, and cwbep, since they have more options than ImageMagick or utilize newer encoders, such as cjpegli.
