FWTools is an excellent suite of free open source conversion tools
whic hyou can download at:
  http://www.remotesensing.org/gdal/

You would use e.g.:

   gdal_translate.exe -a_srs epsg:102758 -co "TFW=YES" in.tif out.tif

This would write a geo-tiff header into out.tif for the coordinate
system defined by epsg code 102758 (Wyoming State Pane) and also write
a world file (TWF).

Actually, that's just the tip of the iceburg of what can be done with FWTools.
