As the mass of the black hole grows greater and greater (from sucking in everything around it) it has an ever increasing gravitational force that pulls its outer-lying matter inward more and more and thus increases its density by decreasing its volume

A black hole can become smaller through a process called Hawking radiation, which occurs when particles and anti-particles are created near the event horizon. If one of the particles falls into the black hole while the other escapes, it causes the black hole to lose a small amount of mass, leading to its shrinkage over time.
