afaik, windows does recognize .png files, but I've had similar problems
with pictures taken with the screenshot app.

you can simply open it with image viewer, and go File > Save As... and
save it as a .jpg file. Tested and works:

                $ file '~/Pictures/test.png' 
                /home/andrew/Pictures/test.png: PNG image, 543 x 126,
                8-bit/color RGB, non-interlaced
                $ file '~/Pictures/test.jpg'
                /home/andrew/Pictures/test.jpg: JPEG image data, JFIF
                standard 1.01
