GPX to GEOJSON
Converting a .gpx font to .geojson repackages the same glyphs and metrics for a different delivery target. Free, private, and validated — the file never leaves your browser.

Converting a .gpx font to .geojson repackages the same glyphs and metrics for a different delivery target. 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.
A .geojson file encodes geographic features as JSON: geometries such as Point, LineString and Polygon, each optionally carrying a free-form properties object, usually collected in a FeatureCollection. It is the format web mapping actually runs on. For this route the practical draw is parses with a standard JSON library — no GIS stack required and a fixed coordinate reference system removes a whole class of projection errors — balanced against verbose and large for dense geometry, with no built-in compression, which is worth knowing before you commit a large batch.
Why convert GPX to GEOJSON?
The practical trigger for this conversion is usually a mismatch: with .gpx, verbose XML — large for the number of points it carries. Switching to .geojson buys you parses with a standard JSON library — no GIS stack required, which is why it is the better fit for rendering geographic data in Leaflet, Mapbox or OpenLayers. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
GPX vs GEOJSON at a glance
| Aspect | GPS Exchange Format (.gpx) | GeoJSON (.geojson) |
|---|---|---|
| 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 | three distinct concepts: wpt waypoints, rte planned routes, and trk recorded tracks made of trkseg segments | coordinate order is longitude, latitude — the reverse of how people say it, and the single most common source of bugs |
| Strongest at | exporting a recorded run, ride or hike from a watch or phone | rendering geographic data in Leaflet, Mapbox or OpenLayers |
| Weak spot | verbose XML — large for the number of points it carries | verbose and large for dense geometry, with no built-in compression |
| Metadata | coordinates, elevation, timestamps and point names are preserved. Vendor extension data such as heart rate is not carried into targets with no equivalent field | geometry and the properties object are preserved. Styling is not part of the format, so a conversion from KML loses that presentation information rather than GeoJSON dropping it |
Pick GEOJSON as the output
Select .geojson in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if GEOJSON 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 GEOJSON file. Outputs keep the original filename with the .geojson extension.
GPX to GEOJSON questions, answered
Will converting GPX to GEOJSON lose quality?
There is no visual quality to lose — gpx is text-oriented and geojson 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 GPX files here?
Yes — the .gpx 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 GEOJSON file work?
Read by Leaflet, Mapbox GL, OpenLayers, QGIS, PostGIS, GDAL and GitHub, which renders it inline. Novus Convert parses it locally and converts to GPX, KML, TopoJSON and WKT.
Will the GEOJSON file be bigger or smaller than my GPX?
It depends on the content: coordinate order is longitude, latitude — the reverse of how people say it, and the single most common source of bugs. Convert one representative file first and compare before batch-processing a large set.
What happens to the metadata in my GPX file?
In .gpx, coordinates, elevation, timestamps and point names are preserved. Vendor extension data such as heart rate is not carried into targets with no equivalent field. 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 GEOJSON back to GPX?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .gpx → .geojson → .gpx is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
