In the Windows world, HiJaak Pro will do batch conversions from various
formats (including TIFF) to various formats (including JPEG and GIF).  In
Windows95, just highlight the files you want to convert, right-click, and
select HiJaak Convert.

In the Unix world, you should explore the PPM utilities.  They're a bunch
of individual commands that convert between graphics formats by way of the
PPM format (Portable PixMap - sort of a Unix Esperanto for graphics) and
can also handle things like resizing if you want to make a set of
thumbnails.  In true Unix style, you're expected to string a set of these
commands together and roll your own shell script to process the entire
directory.
