Moment of inertia can be understood as the spread of mass over a rigid body. It is simply the mass distribution along a chosen axis of rotation. It depends only on mass of the particle and its distance from the axis of rotation. It doesn't depend on angular velocity.

However for conservation of angular momentum L, the relation between moment of inertia I, and angular velocity w, is

L = I w

Therefore, if I increases, w decreases so that the total angular momentum L is a constant. The vice versa is also true. If I decreses, w increases.
