The compressor pedal can sound anything from a subtle barely noticeable effect to a thick, dampened squish.
The benefit of a compressor lies in that every note played will be at nearly the same amplitude, and therefore nearly equal in volume. This will help normalize tones that are sometimes lost in the mix because of complex overtones, and it will result in a more articulate sound and provide a smooth compressed tone while maximizing the punch of your notes
One use for the guitarist is to "clean up" the sound when the player is uneven in their playing.
Another use is in extending sustain. As you strike the note, it's loud so the compressor brings the volume down. As the guitar's signal dies away, the compressor releases, so the note reaching your amp carries on.
Another use is as a safety net to avoid ever outputting too high a signal
Aside from its use as a guitar effect, and its use on other individual tracks, compression is used extensively in mixing and mastering. One of the many possible effects is the "surging" effect in lots of pop and dance, where everything swells to fill the space in between drum beats. Some radio stations even apply compression to their entire output.
