GPX ⇄ KML CONVERTER

GPX (GPS Exchange Format) is designed for GPS devices and outdoor activities like hiking and cycling. It's the standard format for Garmin, Suunto, and fitness apps like Strava. KML (Keyhole Markup Language) is used by Google Earth and Google Maps for displaying geographic data. KMZ is a compressed (ZIP) version of KML that saves space and can include additional files like images. The converter automatically handles all three formats.

Yes! The converter has full KMZ support. Simply upload your KMZ file (exported from Google Earth or other mapping tools), and the converter will automatically extract the KML content, convert it to GPX if needed, and preserve all waypoints and routes. The process is completely automatic.

Select the "Merge Routes" mode at the top, then upload multiple GPX, KML, or KMZ files. Click Convert, and the tool will combine all routes into a single output file. You'll get both GPX and KML versions of the merged route. This is perfect for combining multi-day hiking trips or connecting route segments.

Yes! The converter automatically calculates total distance from your GPS track points using the Haversine formula (accurate for Earth's curvature). Distance is displayed in both kilometers and miles in real-time as you upload files. You'll see the distance both in the statistics bar below the map and in the conversion analytics.

Absolutely! All waypoints, track points, routes, elevation data, timestamps, and metadata are perfectly preserved during conversion between GPX, KML, and KMZ formats. The converter also counts and displays the total number of waypoints and track points automatically, so you can verify everything transferred correctly.

Yes, 100% private! All conversion happens locally in your browser using JavaScript. No data is uploaded to any server, and your GPS routes, waypoints, and location data never leave your device.

Any device or app that exports standard GPX, KML, or KMZ files. This includes GPS watches like Garmin, Suunto, Polar, Wahoo, and Coros. Smartphone apps like Strava, Komoot, AllTrails, Gaia GPS, OsmAnd, MapMyRun, and Ride with GPS. Mapping software like Google Earth, QGIS, ArcGIS, and Garmin BaseCamp. Bike computers like Garmin Edge, Wahoo ELEMNT, and Hammerhead Karoo.

Yes! The converter includes an interactive map with 3 layer options: Satellite imagery (default), Street Map, and Topographic. Your routes are displayed in real-time with colored lines and waypoint markers as soon as you upload files. Click the fullscreen button for a larger view, and use the "Fit all routes" button to zoom perfectly to your tracks.

Select the "Split Route" mode, upload a single GPX, KML, or KMZ file with multiple tracks or segments, then click Convert. The tool will separate each track into individual GPX files. This is useful for extracting specific sections from a long route or separating out-and-back segments.

Yes! You can upload and convert multiple files simultaneously using batch processing. Simply drag & drop or select multiple GPX, KML, or KMZ files. Each file is converted individually, and you can download all results at once as a ZIP archive or download each file separately.
