GPX Files and KMZ Files Compared:
When to Use Each Format
GPX and KMZ are both popular file formats for storing geographic data, but they serve slightly different purposes. Here's how they compare:
What is a GPX file?
A GPX (GPS Exchange Format) file stores GPS data like tracks, waypoints, and routes. It’s a simple XML format designed for lightweight GPS navigation and data sharing between devices.
- Tracking activities like hiking, biking, or running
- Importing/exporting to fitness or mapping apps
- Devices like Garmin, Strava, or Komoot
What is a KMZ file?
A KMZ file is a compressed version of a KML (Keyhole Markup Language) file used primarily with Google Earth. It can include placemarks, images, paths, polygons, and even embedded 3D models.
- Complex map presentations
- Custom icons or embedded images
- Visualizing data in Google Earth
- Sharing entire map experiences (not just coordinates)

Which is better: KMZ or GPX?
It depends on your use case. KMZ is ideal for Google Earth visualizations and rich geographic data with styling options. GPX is best for activity tracking, fitness apps, and GPS devices. Check out our comparison table above to find out which format fits your needs.
Will the converter work offline?
Our tool works best online, but since it runs entirely in your browser, it can also function offline after the initial load—especially in supported browsers like Chrome and Firefox with proper caching.
