Fit File Editor

Change the device on a FIT file

Open a .fit file and relabel the recording device: the manufacturer and the model. Useful when an activity was recorded on a borrowed unit, or you want your history filed under one device. Everything else in the file stays exactly as recorded.

When it helps

  • You rode with a borrowed watch and want the activity filed under yours.
  • An app exported the file with a generic or wrong device name.
  • You're consolidating history onto one platform and want it consistent.
  • A duplicate or retired device keeps showing up on your activities.

How it works

  1. Open your file, or drag it onto the page.
  2. Open the details panel next to the file name.
  3. Pick the manufacturer and the model.
  4. Export the file and upload it.

Questions

Which devices can I choose?
Any manufacturer and product in the official FIT profile: Garmin, Wahoo, COROS, Suunto, Polar, Hammerhead, and more.
Will Garmin Connect and Strava accept the relabeled file?
Yes. FIT File Editor exports a valid .fit file and platforms read the new device on upload. One honest caveat: a few Garmin badges also check the unit's serial number, which stays as recorded.
Does anything else in the file change?
No. Heart rate, GPS, power, laps, and totals stay exactly as recorded. Only the device label changes.
Is it free, and does the file get uploaded?
Free, no account, and the file never leaves your browser.
