Assume that $\unicode[STIX]{x1D6FA}$ and
$D$ are two domains with compact smooth boundaries in the extended complex plane
$\overline{\mathbf{C}}$. We prove that every quasiconformal mapping between
$\unicode[STIX]{x1D6FA}$ and
$D$ mapping
$\infty$ onto itself is bi-Lipschitz continuous with respect to both the Euclidean and Riemannian metrics.
