best freeware for doing batch conversion of jpg to png [closed]
Solution 1:
while irfanview is officially a viewer, it does a pretty good job at he sort of batch conversions you're talking about
Solution 2:
- 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.
