The light-front approach is applied to calculate the electromagnetic current for quark-antiquark bound states for the pion. The pion electromagnetic form factor is obtnaide from the "+" and "-" components of the electromagnetic current in the Drell-Yan frame, with different models of the pi-q\bar{q} vertex and the results for the pion electromagnetic form factor are compared with the experimental data up to 10 [GeV/c]^2 and anothers hadronic models. The rotational symmetry propreties of the pion electromagnetic current related with the zero-modes in the light-front are investigate.
