Why do philosophers say that Immanual Kant’s ideas were like the Copernican Revolution of Philosophy?

In science, the Copernican revolution was the insight that forever changed how we viewed ourselves in the universe. We began to view ourselves more humbly and realized the universe  did not revolve around us. 

Why do people say Kant’s ideas were like the Copernican Revolution of Philosophy? From what I know about Kant’s work and his broader contribution to the enlightenment, I don’t understand what warrants this description of his ideas.

Its just a metaphor, or equivalence. The Copernican revolution was the paradigm shift in cosmology away from geocentrism. Kant's work was (according to this formulation) a paradigm shift in philosophy - especially in epistemology.

What was the Kantian paradigm shift? Instead of imagining our cognition conforms to experience, Kant asks: what if experience conforms to our cognition.

To this end, he described the 'transcendental apparatus' of our minds: the cognitive faculty that has (not just little bits of information but) a way of handling experience which intrinsically imposes an organisation or structure on our experience.
