Like the name says, it compresses the sound.

"A compressor acts as an automatic volume control, progressively decreasing the output level as the incoming signal gets louder, and vice versa. It preserves the note's attack rather than silencing it as with an Envelope Volume pedal. This adjustment of the volume for the attack and tail of a note evens out the overall volume of an instrument. Compressors can also change the behaviour of other effects, especially distortion. When applied to the guitar, it can provide a uniformed sustained note; when applied to instruments with a normally short attack, such as drums or harpsichord, compression can drastically change the resulting sound. Compressors can also be used to smooth out the sound of a guitar or bass guitar. Another kind of compressor is the optical compressor, which uses a light source such as an LED or lamp to compress the signal."

In layman's terms, it squashes your sound into something more manageable, usually adding sustain and changing every element that's before it in the effects chain as well.

Think of this as your normal signal: /\/v\vV\/v\/\/VV\/\/v\/\/VV
This will be your compressed signal: vvvvvvvvvvvvvvvvvv
