Looking for some image software.

I have around 1 million images, all very small, but all in 256 colour, I am looking for a batch convertor to convert them to 32bit colour.
Any one know of any program that can do this?
Many thanks.

xnconvert – free and portable version available. http://www.xnview.com/en/xnconvert/
