From Earth, Pluto has an average apparent visual magnitude of 15.1, and can be as bright as 13.65.
Apparent visual magnitude is defined as the level of brightness of a celestial object as observed from Earth. The smaller the number is, the brighter the object. Objects with a value that's equal to or less than 6 can be seen with the naked eye, but those with higher numbers will require the use of binoculars (up to a value of about 10) or a telescope (27 for an 8m telescope; 32 for the Hubble Space Telescope).
For comparison, here are the apparent visual magnitudes of some well-known celestial bodies:
Our Sun: -27
Full moon: −13
Venus: −5 (maximum)
Vega: 0
Polaris: 2
