  Using the BRST--BV approach, we consider totally symmetric arbitrary integer
spin conformal fields propagating in flat space. For such fields, we obtain the
ordinary-derivative BRST--BV Lagrangian that is invariant under gauge
transformations. In our approach, the ordinary-derivative Lagrangian and gauge
transformations are constructed in terms of the respective traceless gauge
fields and traceless gauge transformation parameters. We also obtain a
realization of conformal algebra symmetries on the space of fields and
antifields entering the BRST--BV formulation of conformal fields.
