Conversion of CMB photons to axion like particles is one of the most sensitive way to look for these pseudoscalar particles. I will review the physics of conversion which is similar to neutrino oscillations. I will discuss different signatures of axions in the CMB maps and constraints on axion like particles from current and future CMB experiments.
