FIT file viewer

Open a FIT file from your Garmin, Wahoo, Coros or Zwift and see the route, the elevation and heart-rate profile and the main numbers. No account and no upload: the FIT file is read in your browser.

How to open and view a FIT file

  1. 1Drop your .fit file in, or click to choose it
  2. 2Look at the route, the profile and the numbers
  3. 3Save a copy as GPX, TCX or FIT if you need one
  4. The track, elevation, heart rate and stats of the activity.

What you get

  • Nothing is uploaded.The FIT file is decoded by your browser, on your own device.
  • No Garmin software needed.FIT is a binary format; the tool reads it for you.
  • Sensor data comes along.Heart rate, cadence, power and temperature are used when they are in the file.

What you can do

  • Open a FIT activity and see its route drawn as a line.
  • Read distance, moving time, elapsed time, elevation gain, average and max heart rate, average and max speed and the number of points.
  • See the elevation and heart-rate profile along the distance.
  • Open several FIT files at once, or mix in GPX and TCX. They are shown as one activity, in time order.
  • Switch to the other modes of the same tool to crop, split, reverse or simplify the activity, and save it as GPX, TCX or FIT.

Good to know

  • The tool needs recorded activity data. A FIT file without activity records, such as a workout plan or a settings file, is refused with a message.
  • A FIT file that is cut off or damaged is still opened: the points before the damage are kept and a warning says so.
  • A FIT file with several chained recordings is read in full.

Questions

How do I open a FIT file without Garmin software?

Drop it on this page. It is read in your browser and shown with the route, the profile and the stats.

Is my FIT file uploaded?

No. It stays on your device and is never sent anywhere.

Can I turn the FIT file into GPX?

Yes. Open the file, then use "Save GPX". Position, elevation, time, heart rate and cadence are kept.

Which devices make FIT files?

Garmin, Wahoo, Coros, Suunto and Zwift all write FIT, and so do many apps that export an activity.
