What this format is
Most web tools only decode FIT. This page encodes one. Garmin Connect will treat it as a new activity. Device settings from a real unit are not invented.
How to get the file
- From Garmin Connect
- 1. If you already have FIT, you do not need this page. Use it when a map app gave you GPX.
- From Strava
- 1. Export GPX from the activity, convert here, import the FIT elsewhere.
What is kept and what is lost
| Kept | Lost or missing |
|---|---|
| GPS, time, HR, cadence, power from the GPX extension | Waypoints, routes, and Garmin device settings that GPX never had |
Questions
Will Garmin Connect import the FIT?
That is the point. Import as a new activity. Device settings from a real Garmin unit will not be invented.
Are sensors kept?
Heart rate, cadence and power in Garmin’s GPX extension become FIT record fields.
Why is this scarce?
Most web tools only decode FIT. Writing a valid FIT in the browser is the harder direction.
Indoor GPX without GPS?
If the GPX has no lat/lon the FIT will have time and sensors only.
