Although you can fire-up the GIMP to convert an image from one format to another, it's something of a sledgehammer to crack a nut, and time-consuming too. An easier way is to use the Imagemagick software. You'll need to use Synaptic to install it first, however (search for and install the imagemagick package). Once installed, simply use the convert command. The command is intelligent enough to work out what you're trying to do from the filenames you give it. For example, the following will use Imagemagick to convert filename.jpg into a bitmap file:

$ convert filename.jpg filename.bmp
