Convert files
Convert a route between GPX, KML, TCX, GeoJSON and FIT. Choose the source format or have it detected automatically, then pick the format you want to convert to.
Which formats
This tool reads GPX, KML, TCX, GeoJSON and Garmin FIT files, and writes to GPX, KML and GeoJSON. Upload your file, choose which format to convert from and to, and download the result.
The conversion happens entirely in your browser. Your file is not sent to a server and no data is stored.
Reading FIT files uses a library that loads once in your browser. Your file itself is not uploaded; the processing stays local on your device.
