KML to GPX conversion takes just two clicks in ExpertGPS. Now you can download KML to your GPS and convert Google Earth places and routes to waypoints and tracks on your GPS receiver. You can copy KML placemarks from your My Places folder in Google Earth and paste them directly into ExpertGPS. Or, you can open any KML file in ExpertGPS by clicking Import on the File menu. ExpertGPS uses GPX as its native format, and outputs 100% compatible GPX files that work with any GPS receiver from Garmin, Magellan, Lowrance or other GPS manufacturer. ExpertGPS was written by TopoGrafix, the maintainers of the GPX File Format Standard, so you know you're getting a proven KML to GPX converter.
Unlike other KML - GPX converters that can't upload and download your GPS data, ExpertGPS is a complete solution that will download KML files to your GPS receiver in two easy steps. And ExpertGPS does a much better job converting your GPX data back to KML, because ExpertGPS creates custom KML files for each GPS receiver, so the KML placemarks in Google Earth have the exact same symbols as the waypoints did on your GPS receiver.
