A teleconverter increases the focal length of your lens, for example: a 400mm lens with a 1.4x would give you a focal length of 560mm, but you lose an f/stop (f/5.6 would become f/8) and a 2x doubles the focal length (400 becomes 800mm) and you lose two stops (f/5.6 becomes f/11). Teleconverters work best with long prime lenses rather than zooms, although you can get usable results with zooms.
Here are some examples:
This was taken with a Canon 30D, a Canon 100-400 and a 1.4X teleconverter.
1/250s f/8.0 at 560.0mm iso400
This was taken with a Canon 30D, a Canon 200 f/2.8L and a 2X teleconverter.
1/200s f/5.6 at 400.0mm iso250
