KMZ to GPX: convert a KMZ file online
A KMZ is a zipped KML, the default export format of Google Earth and My Maps. Drop it: the tool unzips it, shows it and gives you the GPX. For other formats, see the GPX conversion tool.

How to convert KMZ to GPX
1. Drop the KMZ
No need to unzip it first: the tool opens the archive and reads the doc.kml file inside.
2. Check it on the map
The routes and placemarks in the KMZ appear, with distance and elevation gain when the file has elevations.
3. Download the GPX
The GPX downloads under the KMZ’s name. You can also get the unzipped KML.
KMZ, KML and GPX: what is the difference
KMZ is not another track format: it is a ZIP archive holding a KML file (often named doc.kml) and sometimes the images and icons it uses.
| KMZ | GPX | |
|---|---|---|
| What it is | ZIP archive: a KML and its images | XML file, readable as is |
| Made by | Google Earth, Google My Maps (default export) | watches, bike computers, sports apps |
| Contents | those of the KML: lines, placemarks, polygons, styles | tracks, routes, waypoints |
| Size | smaller, compressed | larger, uncompressed text |
What is kept and what is lost
What is kept
- the routes in the main KML (doc.kml, or the first KML found in the archive), one GPX track per route;
- placemarks, as waypoints with their name;
- elevation and, for gx:Track paths, point times.
What is lost
- images, icons and photos stored in the archive;
- styles and folders, as with a KML;
- network links (NetworkLink): a KMZ that only points to online data holds no track to convert.
Frequently asked questions
Do I need to unzip the KMZ first?
No. The tool opens the archive itself. If you have already unzipped it, drop the .kml file instead.
The message says the archive has no KML
The file is probably not a Google Earth KMZ (another ZIP that was renamed, for instance). Open it in Google Earth and save it again as KMZ or KML.
My Maps gives me a KMZ. Is that normal?
Yes. Google My Maps exports KMZ by default; a checkbox gives you a KML instead. The tool reads both.
Is my file uploaded to a server?
No. Unzipping and conversion happen in your browser.
