Drop one or more .kml files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
KML to GPX
Converting a .kml font to .gpx repackages the same glyphs and metrics for a different delivery target. Free, private, and validated — the file never leaves your browser.

Converting a .kml font to .gpx repackages the same glyphs and metrics for a different delivery target. A .kml file is Keyhole Markup Language: an XML format describing geographic features together with how they should look and how a camera should view them — placemarks, paths, polygons, styles, icons and overlays. It carries presentation, which is what separates it from GPX and GeoJSON.
A .gpx file is the GPS Exchange Format: an XML schema for waypoints, routes and recorded tracks, where every point carries a latitude and longitude and may carry elevation and a timestamp. It is what a GPS watch or handheld exports. For this route the practical draw is universally supported across GPS devices and fitness platforms and distinguishes planned routes from recorded tracks, which matters in practice — balanced against verbose XML — large for the number of points it carries, which is worth knowing before you commit a large batch.
Why convert KML to GPX?
The practical trigger for this conversion is usually a mismatch: with .kml, verbose, and mixing styling with data makes documents large. Switching to .gpx buys you universally supported across GPS devices and fitness platforms, which is why it is the better fit for exporting a recorded run, ride or hike from a watch or phone. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
KML vs GPX at a glance
| Aspect | Keyhole Markup Language (.kml) | GPS Exchange Format (.gpx) |
|---|---|---|
| Format type | Text-based — characters and structure, so there is no visual quality loss | Text-based — characters and structure, so there is no visual quality loss |
| How it stores data | placemark elements pair a geometry with a name, description and style reference | three distinct concepts: wpt waypoints, rte planned routes, and trk recorded tracks made of trkseg segments |
| Strongest at | displaying geographic data in Google Earth or Google Maps | exporting a recorded run, ride or hike from a watch or phone |
| Weak spot | verbose, and mixing styling with data makes documents large | verbose XML — large for the number of points it carries |
| Metadata | geometry, names and descriptions are preserved. Styling, icons and camera viewpoints have no equivalent in GeoJSON or GPX and are not carried across | coordinates, elevation, timestamps and point names are preserved. Vendor extension data such as heart rate is not carried into targets with no equivalent field |
Pick GPX as the output
Select .gpx in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if GPX is selectable, the route is real and validated.
Convert on your device
Press Convert. The font tables are parsed and rewritten locally with fonteditor-core; glyph outlines, hinting, and kerning survive the trip.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid GPX file. Outputs keep the original filename with the .gpx extension.
KML to GPX questions, answered
Will converting KML to GPX lose quality?
There is no visual quality to lose — kml is text-oriented and gpx is text-oriented, so the question is structural fidelity. Text, ordering, and basic structure are preserved; complex layout, embedded objects, and styling beyond the target's model are simplified.
Is it private to convert KML files here?
Yes — the .kml file is processed inside your browser tab and never uploaded. The font tables are parsed and rewritten locally with fonteditor-core; glyph outlines, hinting, and kerning survive the trip. Close the tab and the file is gone from memory.
Where will the GPX file work?
Read by Garmin, Strava, Komoot, QGIS, Google Earth and the whole OpenStreetMap ecosystem. Novus Convert parses waypoints and track segments locally and converts to GeoJSON and KML.
Will the GPX file be bigger or smaller than my KML?
It depends on the content: three distinct concepts: wpt waypoints, rte planned routes, and trk recorded tracks made of trkseg segments. Convert one representative file first and compare before batch-processing a large set.
What happens to the metadata in my KML file?
In .kml, geometry, names and descriptions are preserved. Styling, icons and camera viewpoints have no equivalent in GeoJSON or GPX and are not carried across. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
Can I convert GPX back to KML?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .kml → .gpx → .kml is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
