  The Dyson-Schwinger equations of QCD, truncated to ladder-rainbow level, are
used to calculate meson form factors in impulse approximation. The infrared
strength of the ladder-rainbow kernel is described by two parameters fitted to
the chiral condensate and f_pi; the ultraviolet behavior is fixed by the QCD
running coupling. This obtained elastic form factors F_pi(Q^2) and F_K(Q^2)
agree well with the available data. We also calculate the rho to pi gamma and
K* to K gamma transition form factors, which are useful for meson-exchange
models.
