Geo & 3D converters
Convert geodata and 3D formats locally in your browser: GeoJSON, KML, GPX, WKT plus STL, OBJ and glTF. No upload.
This area brings together geodata and 3D models: convert map and location formats like GeoJSON, KML, GPX, WKT or TopoJSON and 3D formats like STL, OBJ or glTF. With it you can exchange GPS recordings, map data or models between programs.
Whether a route track from a hike or a 3D model for the printer, the conversion happens locally in the browser, with no upload. So even location data, which can reveal a lot about you, stays on your device.
