Convert GPX to KML for Google Earth
Converting GPX to KML is easy in ExpertGPS. Open any GPX file in ExpertGPS. ExpertGPS uses GPX, the GPS Exchange Format, as its native file format, unlike other GPX converters that throw away most of your GPX data on import. View your GPX file over the maps in ExpertGPS, and if you like, change waypoint symbols or add color to your tracklogs so you'll get a better-looking result in Google Earth. Press F7, the View in Google Earth command. ExpertGPS will convert your GPX file to KML and automatically zoom to the KML data in Google Earth's map viewer.
ExpertGPS is the best KML converter for your GPX files
ExpertGPS does a much better job converting GPX to KML than other GPX to KML converters, because ExpertGPS creates custom KML files with the same GPS symbols used in your GPX file, so the KML placemarks in Google Earth have the exact same icons as the waypoints did on your GPS receiver. For example, here are the KML placemarks displayed for a GPX file from a Garmin Colorado 400t:
