KMZ is simply a KML file (plus any referenced icons or overlays) compressed into a single ZIP archive with a .kmz extension. It's the format Google Earth produces when you save a place, because bundling everything into one compact file makes maps easy to email and share. Under the hood it's still KML, so a KMZ converts cleanly to and from every other geographic format.
Need the other direction instead? GPX is the GPS Exchange Format for tracks, routes and waypoints. GPX (GPS Exchange Format) is the open XML standard for GPS data, supported by virtually every handheld GPS unit, fitness watch and outdoor app (Garmin, Strava, Komoot, AllTrails). It stores waypoints, routes and recorded tracks with timestamps and elevation. If your data comes off a GPS device or needs to load onto one, GPX is the format you want.

KMZ to GPX — FAQ
- How do I convert KMZ to GPX?
- Upload your .kmz file using the converter above (drag & drop or click to browse). GeoMaps converts it to GPX instantly in your browser and gives you a .gpx file to download. No software to install and no signup required.
- Is the KMZ to GPX converter free?
- Yes — it's completely free with no usage limits, watermarks or account needed. We offer it as a free tool from GeoMaps, the platform for turning your data into interactive maps.
- Is my data private? Are my files uploaded to a server?
- No. The conversion runs entirely in your web browser using JavaScript — your file is never uploaded to any server. Because nothing leaves your device, it's safe for sensitive or confidential data and works even offline once the page has loaded.
- Can I convert GPX back to KMZ?
- Yes. Use our GPX to KMZ converter for the reverse conversion — every format on GeoMaps converts both ways.
- How large a file can I convert?
- Because conversion happens in your browser, the limit is your device's memory rather than a server quota — files up to tens of megabytes convert comfortably on a typical laptop. Very large datasets may be slower depending on your machine.
