GPX to KMZ, Explained
GPX is the open format GPS devices, Garmin units, and apps like Strava export tracks, routes, and waypoints in — but Google Earth and Google Maps work in KML and KMZ instead. Converting GPX to KMZ moves a GPS track out of device-specific software and into the viewer almost everyone already has installed.
Why This Converter
Amazing Features, Free
- Tracks, routes, and waypoints — all at once. Every element in your GPX file converts, not just one type.
- Real KMZ, not a renamed KML. The output is properly zipped, the exact format Google Earth saves and shares by default.
- Names carry over. Track, route, and waypoint names from your GPX become placemark names in the KMZ.
- Instant stats before download. See the feature count and geometry types found, so you know the conversion worked before opening the file.
- Nothing is ever saved. Converted in memory over an encrypted connection and forgotten the moment the response is sent.
How It Works
Convert GPX in 3 Steps
- Upload your GPX. Drop or choose a .gpx file — up to 5MB.
- Convert instantly. Click Convert. Every waypoint, route, and track is read and turned into a KMZ in memory, never saved.
- Download the KMZ. Get a ready-to-open .kmz file, named for immediate use in Google Earth or any GIS software.

Frequently Asked Questions
What is a GPX file?
GPX (GPS Exchange Format) is an open, XML-based format for GPS data — waypoints, routes, and tracks — exported by GPS devices, Garmin, Strava, and most hiking or cycling apps.
What is a KMZ file?
KMZ is a zipped KML file — the format Google Earth and Google Maps use natively. It packs the same points, lines, and polygons as KML into one smaller, single file instead of a loose .kml.
How do I convert GPX to KMZ?
Upload your .gpx file above and click Convert. This gpx to kmz converter reads every waypoint, route, and track in the file and builds a single ready-to-use .kmz in seconds.
Is this a free GPX to KMZ converter?
Yes — convert gpx to kmz online for free, no signup, no file limit beyond 5MB, no watermark.
Does it convert tracks, routes, and waypoints, or just one?
All three. A GPX file can contain waypoints, routes, and tracks together, and this gpx kmz tool converts every one of them into its own placemark in the output KMZ.
Do you store the GPX files I upload?
No. Your file is converted entirely in memory on our server, over an encrypted connection, and is never written to disk, logged, or kept after the response is sent.
What's the difference between KML and KMZ output?
KML is a plain XML text file; KMZ is that same KML zipped into one compact file. Google Earth opens either, but KMZ is the format it saves and shares by default, which is why this tool outputs KMZ directly instead of plain KML.
