How to convert FIT to GeoJSON

  1. Add your FIT activities

    Drop FIT files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.

  2. GeoJSON is already chosen

    Press Convert. There is nothing else to set. The work happens in this tab.

  3. Download

    Save the GeoJSON, or download everything as one ZIP if you converted several files.

Why ToAny

  • Private by construction

    The FIT to GeoJSON converter is part of this page and runs inside your browser. Your activities are never sent to ToAny or to anyone else.

    Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.

  • Free, without an account

    No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.

FIT to GeoJSON: what to expect

FIT is binary, so map tools and text editors cannot read it. GeoJSON is plain JSON that web maps and GIS software read directly. FIT is at home in workouts recorded by sports watches and bike computers; GeoJSON is the usual choice for points, lines and areas on the web.

Every format is read into plain GeoJSON features and written out from there, so coordinates, names and properties carry over wherever the target has a place for them. Only recordings with GPS positions can be converted; an indoor workout with no route is refused. Time and elevation are kept, and so are heart rate, cadence and power where the watch recorded them. Coordinates are written longitude first, then latitude, as GeoJSON requires.

FIT vs GeoJSON

FIT

Garmin FIT activity

FIT is the binary format Garmin watches and bike computers write for every activity. It is compact and carries sensor data such as heart rate, cadence and power alongside the GPS track. Wahoo, Zwift and many other devices use it too.

Opens in Garmin Connect, Strava, TrainingPeaks and most fitness platforms; not map tools

GEOJSON

GeoJSON map data

GeoJSON describes geographic features, points, lines and polygons, with their properties as plain JSON. It is the standard format for web maps. Coordinates are in WGS 84 and written longitude first, then latitude, the reverse of how most people say them.

Opens in QGIS, Leaflet, Mapbox, geojson.io, GitHub's map view and most GIS tools

Questions

Are my activities uploaded anywhere?

No. The FIT to GeoJSON conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.

Is anything lost when converting FIT to GeoJSON?

The values are kept. Anything GeoJSON has no way to express, such as formatting, formulas or nesting, is simplified or left out.

Can I convert several FIT files at once?

Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.

How do I convert FIT to GeoJSON on Windows, Mac, iPhone or Android?

The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the FIT file, press Convert and save the GeoJSON. There is nothing to install.

Is there a file size limit?

Yes. Files up to 200 MB are accepted; a larger file is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
