No. Windows paint does not support transparency, although using color purple RGB: 255,0,255 could be used as a transparent color. Some programs pick it up, but MS Paint does not natively support transparency. Paint.net (free program) does support transparency, and is easy to use. It even does support alpha-transparency.

Conversion time/speed is not a problem but I do feel safer if it took a tad bit longer than XnConvert which converted 407 BMPs to PNG, 0 compression in 39 seconds. I’m not sure if that’s normal. You shouldn’t be that concerned about speed in a conversion process like this since BMP and PNG are lossless image formats, but PNG is lossless and ...

It's the JPEG. The keyword here is visible. The entire reason for JPEG working so well is that you can quantize away lots of high frequencies before the human visual system can even perceive any artifacts. Also note that before artifacts (like ringing) become present, the picture will simply lose high frequencies. Without a reference picture to compare ...
