The charge and transition form factors of pions ($F_\pi$, $F_{\pi\gamma}$, and $F_{\pi\gamma^*}$) are studied in the light-front quark model (LFQM). We find that our results for $F_\pi$ and $F_{\pi\gamma}$ agree well with experiment. Furthermore, the mixing of $\eta$ and $\eta'$ is considered. We also calculate $F_{\eta\gamma}$ and $F_{\eta'\gamma}$ and compare them with the data.
