  We consider weighted composition operators, that is operators of the type $g
\mapsto w \cdot g \circ f$, acting on spaces of Lipschitz functions. Bounded
weighted composition operators, as well as some compact weighted composition
operators, have been characterized quite recently. In this paper, we provide a
different approach involving their pre-adjoint operators, namely the weighted
Lipschitz operators acting on Lipschitz free spaces. This angle allows us to
improve some results from the literature. Notably, we obtain a distinct
characterization of boundedness with a precise estimate of the norm. We also
characterise injectivity, surjectivity, compactness and weak compactness in
full generality.
