| contents | We prove for a morphism $f \colon X \rightarrow S$ locally of $^+$weakly finite type, separated and taut, where $X$ is a weakly square complete adic space and $S$ a square complete and stable adic space, there exists a universal vertical compactification $f' \colon X' \rightarrow S$. This provides a generalized version of Huber's proof of universal compactification of morphisms between analytic adic spaces. Notably, we will see that for the compactification, it is not necessary to assume that the adic spaces are locally Noetherian. In the fourth section we give an explicit and simple construction of $X'$. |
