We study when multiplication by a weight can turn a non-compact composition operator on \(H^2\) into a compact operator, and when it can be in Schatten classes. The \(q\)-summing case in \(H^p\) is considered. We also study when this multiplication can turn a compact composition operator into a non-compact one.
