pressure effect on entropy

Why does entropy decrease when pressure increases?

Since pressure is increasing, that means volume is decreasing, therefore there is less space for molecules to spread out, therefore less entropy.

Right, when pressure increases, the inverse happens to volume. Entropy is the amount of possible positions that thing can have so when there is less space, the options for the different amount of positions it can hold are less so therefore, entropy is decreasing.
