I will discuss how microlensing from line-of-sight galaxies in multiply imaged quasars can be used to constrain the mass fraction in massive compact objects. The statistics of microlensing events, which have been used to determine the mass fraction in smoothly distributed dark matter versus small compact objects, can also place limits on populations of intermediate-mass black holes. This method can be used to derive a new constraint on massive primordial black holes and may also have implications for studies of black hole merger histories.
