KML / KMZ to GPX Converter
Send Google Earth placemarks and paths to a Garmin, a phone GPS app or a bike computer. Waypoints and tracks, converted in your browser.
Accepted: .kml, .kmz. Up to 20.0 MB, converted on your device.
Your file never leaves your device. Nothing is stored on any server.
Google Earth is handy for planning a route or marking sample points, but GPS receivers and most outdoor apps want GPX. This converter reads the KML or KMZ, writes every point as a GPX waypoint and every path as a track, keeps names, descriptions and elevation, and produces a file that Garmin devices and apps like OsmAnd, Locus Map, Gaia GPS and Komoot import directly.
How to convert KML to GPX
Drop a .kml or .kmz from Google Earth, Google My Maps or any other source. The preview shows the points and paths that were found.
Choose which attribute becomes the waypoint or track name if the file has more than one text field.
Click Convert and download the .gpx, then copy it to your device or import it into your GPS app.
What is a KML file?
KML (Keyhole Markup Language) is an XML format for geographic data made popular by Google Earth and Google Maps. It stores points, lines and polygons in WGS84 latitude and longitude, groups them in folders, and can carry attributes in ExtendedData elements or in HTML descriptions.
What is a GPX file?
GPX (GPS Exchange Format) is an XML format used by handheld GPS receivers, Garmin devices and outdoor apps. It stores waypoints (wpt), routes (rte) and tracks (trk) with optional elevation and timestamps, always in WGS84.
Why use this converter
Waypoints and tracks
Points become <wpt> waypoints and lines become <trk> tracks with one segment per part. Elevation from the KML is written as <ele> when present.
Names and notes kept
Placemark names and descriptions are written to the GPX name and desc elements, so the labels you see in Google Earth appear on the GPS too.
Works with common devices
The output is GPX 1.1 and has been checked with Garmin BaseCamp, OsmAnd, Locus Map, Gaia GPS and QGIS.
Nothing is uploaded
Everything runs in your browser. Your files are never uploaded, so confidential survey, cadastral or forestry data stays on your computer.
Frequently asked questions
Are attributes lost when converting KML to GPX?
GPX only has a few standard fields, so the placemark name goes to name, the description to desc and altitude to ele. Other ExtendedData fields are not part of the GPX standard and are not written; if you need them, convert to CSV or shapefile instead.
What coordinate system does the GPX use?
GPX is always WGS84 latitude/longitude, the same as KML, so coordinates are copied without transformation and match what your GPS shows.
My KML has folders, polygons and MultiGeometry. What happens?
Everything is written into one GPX. Points from all folders become waypoints and paths become tracks. Polygons have no equivalent in GPX, so their outer boundary is written as a track and a note tells you how many were converted that way.
Is the KML to GPX converter free, and is my file uploaded?
Free, no account, and the file stays in your browser. Nothing is uploaded, which also means it works on a weak mobile connection once the page is open.
Which devices and apps open the GPX?
Garmin handhelds and bike computers (via BaseCamp or by copying to the GPX folder), OsmAnd, Locus Map, Gaia GPS, Komoot, Strava, Wikiloc, Google Earth, QGIS and ArcGIS.
Should I create waypoints, routes or tracks?
Points are written as waypoints and lines as tracks, which every device supports. Routes (rte) are not generated because many devices recalculate them; if you need a route, most GPS apps can convert a track to a route on import.
