Primordial black holes (PBHs) could have formed very early on in the history of the universe after inflation ended. They are a viable dark matter candidate and represent a unique probe to study the small scales of the early universe, not visible by other means. I will discuss how PBHs have been used to constrain the small scales, and how this depends strongly on the non-Gaussianity parameters, as well as how PBHs can be used to constrain the large scales in the early universe.
