best freeware for doing batch conversion of jpg to png

Question

Which is the best freeware for converting jpg files in different folder to png in a batch process on a windows xp?

I thought for sure we'd had this Q, but the other ones were about linux. Anyway, Wil's answer, imagemagick, applies here also.

while irfanview is officially a viewer, it does a pretty good job at he sort of batch conversions you're talking about

nconvert from xnview - batch utility to convert graphic files, support of more than 400 graphics formats!
xnview by itself (if you like GUI tools)
imagemagic (windows version is here)

irfanview is ugly, IMHO.

FastStone Photo Resizer lets you convert images in batch mode. It supports JPEG, BMP, GIF, PNG, TIFF and JPEG2000 formats.

x2y can also convert multiple images from different directories to a new format in batch mode.
