Model-independent compact representations of imaginary-time data are presented in terms of the intermediate representation (IR)of analytical continuation. We demonstrate the efficiency of the IR through continuous-time quantum Monte Carlo calculations of an Anderson impurity model. We find that the IR yields a significantly compact form of various types of correlation functions. This allows the direct quantum Monte Carlo measurement of Green's functions in a compressed form, which considerably reduces the computational cost and memory usage. Furthermore, the present framework will provide general ways to boost the power of cutting- edge diagrammatic/quantum Monte Carlo treatments of many-body systems.
