In this note we prove a correspondence, first found by Smoczyk in the hypersurface case, between conformal solitons to the mean curvature flow in an ambient manifold N and minimal submanifolds in a different space \documentclass{article}\usepackage{amssymb}\begin{document}\pagestyle{empty}$N\times \textbf {R}$\end{document}. This naturally leads to a new natural stability notion for conformal solitons. We show that this corresponds to the recent Colding‐Minicozzi's F‐stability for codimension one self‐shrinkers in euclidean space. In this spirit we can give some classification results for stable conformal solitons, answering two questions of Smoczyk.
