It's generally done within graphic design software. Ideally it should never be done, or very little. Some fonts lend themselves to a little forcing, and some none at all (like Futura or Avant Garde), but the typeface designers design them in a certain way for a reason. If you need a more condensed font, choose a font that is more condensed in it's design.
