Online GPX, KML & GeoJSON map editor

Load your GPX, KML and GeoJSON files onto one map, clean up the points and lines by hand, and export to whichever format you need next — the hub’s little route workshop in a browser tab. Everything stays on your device: no upload, no account, no fuss. This is one of the file tools you won’t find on the sister sites.

Runs in your browser — your location is never stored.

What you can do

This is a full map workspace, not just a viewer:

Import one or several GPX, KML or GeoJSON files at once.
See every track, route, waypoint and shape together on one map.
Rename or delete saved maps, remove individual features, and drag points to reposition them.
Export or convert any map to GPX, KML or GeoJSON in a tap.

Your files stay private

Everything happens in your browser. Imported maps are kept in your browser’s local storage (IndexedDB), so they are still here when you come back — but they are never sent to a server, and there is no account to create.

Works with every common map format

GPX is the format GPS watches and apps use, KML is what Google Earth and Google Maps read, and GeoJSON powers web maps and GIS tools. The editor reads and writes all three, so you can move data between them freely.

Frequently asked questions

Is my data uploaded anywhere?

No. Your files are read, edited and stored entirely in your browser — nothing is sent to a server and no account is needed.

Which formats can I import and export?

GPX, KML and GeoJSON. You can import any of them and export to any of them, so the editor doubles as a converter.

Will my maps still be here when I come back?

Yes, as long as you use the same browser on the same device. Saved maps are kept in local storage; clearing your browser data removes them.

Can I edit the geometry?

You can drag point markers to move them and delete individual features. Full drawing of new lines and polygons is on the roadmap.
