By default, all software supports multiple file extensions. Google Maps supports at least 2 different file extensions. The basic files that Google Maps supports are .KML. However, not all of the extensions listed on the list are always used to save the effects of work in Google Maps. Very often, files with such extensions are used as source data files used by Google Maps.
Google Maps can be used to convert file formats between the file extensions listed below. You can open a file with one of the file extensions below via Google Maps and try to save it in another file format, also supported by Google Maps.
