'die Erweiterung' and 'die Extension' can both mean that something is made larger or that an additional part is added to something that already exists. 'Erweiterung' is the normal German word and fits in many areas, for example with buildings, services, or software. 'Extension' sounds more technical and is used especially in certain fields. In computing, 'Extension' can also mean a file name extension, for example '.pdf'.
