KMZ → GPX

Learn about the formats: What is GPX? What is KMZ?

Convert KMZ geographic data files containing Google Earth landmarks into GPX format instantly. This tool is essential for outdoor enthusiasts and navigators transferring routes to dedicated GPS devices.

KMZ is a compressed version of KML used primarily by Google Earth, often storing visual overlays, custom icons, and hierarchical folders alongside coordinates. GPX is an XML-based open standard built specifically for routing, tracks, and waypoints used by hiking GPS units like Garmin. When converting KMZ to GPX, the converter extracts the underlying spatial coordinates, paths, and trackpoints from the compressed archive and structures them into standard GPX schema.

The conversion between these geo-data formats happens without loss, meaning your coordinate precision and track integrity are fully preserved. The file size changes only insignificantly during the process due to XML markup adjustments.

Tips

Ensure your KMZ file contains actual vector tracks or waypoints rather than just raster map overlays, as GPX cannot render raster images.
If your KMZ file includes multiple folders, check your device settings after importing to organize tracks correctly.
Clean up unnecessary placemarks in Google Earth before converting to keep your GPX file lightweight for handheld GPS units.

Common use cases

Transferring hiking trails planned in Google Earth (KMZ) onto a Garmin or Wahoo handheld GPS device (GPX).
Preparing cycling routes created via desktop mapping tools for offline navigation on a bike computer.
Importing travel logs and waypoints into specialized GIS software or mobile trekking apps that require GPX input.
