About Converting GPX to KMZ
A GPX file is what your watch, bike computer or handheld GPS produces: a plain XML list of waypoints, routes and tracks. It is excellent for devices and unremarkable to look at. Google Earth, on the other hand, will drape that same track over satellite imagery and terrain, let you fly along it, and show the elevation profile against the real landscape. To get there your track needs to be KML, and specifically KMZ — a ZIP archive with the KML inside as doc.kml.
This converter reads every waypoint and track point out of your GPX and writes them as KML placemarks and paths, then packages the result as a KMZ. Choosing KMZ over plain KML is not cosmetic: it is a single compressed file, typically a fraction of the size, which matters when a recorded ride holds tens of thousands of track points and you want to email it or attach it to a report.
Common use cases
- Viewing a recorded ride, run or hike draped over Google Earth’s terrain and imagery
- Sharing a route as one compact file that opens with a double-click on any desktop
- Presenting a field survey or site visit to someone who has Google Earth but no GIS software
- Adding a GPS track to a report, proposal or planning document as a viewable attachment
- Archiving a route in a format that stays readable without the original device or app
Tips for best results
- KMZ is the better choice over KML for anything with a lot of track points: the archive compresses the repetitive coordinate text heavily, often to a small fraction of the original.
- Elevation from your GPX is preserved in the coordinates, so Google Earth can draw the track against terrain rather than flat on the ground.
- Waypoints become individually clickable placemarks with their names intact, so a route with marked stops stays navigable in Google Earth.
- The output is byte-for-byte identical for the same input every time — the archive carries a fixed timestamp, so nothing about when or how you uploaded leaks into the file.
