compression

I'm working with images of scanned books, so hundreds of high resolution pictures. I'm doing conversion work with Photoshop Elements - I can quickly save them to uncompressed TIFF, but converting to compressed PNG using a single thread takes ages.

Do you know a software, ideally simple and free, that would batch convert those TIFFs to PNG in a multi-threaded manner (4 to 8 simultaneous files) to take advantage of those cores and cut converting times? I'm not too worried in slight variations in final size.
