how does an airplane compressor work?

Doesn’t the fans in the compressor stage just push the air towards the back of the engine and not compress the air?

A compressor stage has two parts, a rotor and a stator. The rotor spins, the stator doesn’t. The spinning rotor pushes the air into the stator. The stator slows the air down and reduces the space available to the air, which is what actually compresses the air. This repeats over several stages to achieve a very high compression.
