Think what you’re saying here is engine pressure ratio, or EPR. Ratio across the entire engine, not at a particular location, or station. The speed of the air doesn’t change that much after hitting the inlet and first stage of the compressor. A series of blades do accelerate the air then the air passes through a set of stators which are divergent ducts which slow the air converting that energy into pressure. This happens across multiple stages. At the end of the compressor is a diffuser which acts like an extra special stator. Air is at the highest pressure here. On a large modern engine it could be 800psig and over 1000F. This is simplified, there are things that need done with a compressor to get it working across the operating range.

Reply to comment by zutonofgoth in TIL that passenger jet engines produce most of their thrust from fan at the front, not from the jet exhaust, and that this is called a high-bypass engine. by Rilot
