The opensource BioImage Convert may do this since it handles a variety of
file types:

http://bioimage.ucsb.edu/downloads/BioImage%20Convert

They have executables for Windows, Mac, and Linux.

An example from their website for making tiles is:

imgcnv -i MY_INPUT_IMAGE.jpg -o MY_OUT_FOLDER/MY_OUT_BASE_NAME.jpg -t
jpeg -tile 256


Alternatively, there's a powerful Python script "tilemaker.py" that is
easily modified for special tasks.

http://code.google.com/p/panojs/source/browse/trunk/scripts/tilemaker.py?r=2

although it handles a more limited set of file types supported by the
Python PIL library.
