What is FIT?
FIT is the compact binary format Garmin, Wahoo and Coros watches and bike computers record in — small and rich in data, but hard to open directly.
What is GPX?
GPX (GPS Exchange Format) is the universal, human-readable XML standard for GPS tracks — understood by almost every map, route planner, watch and hiking site.
Why convert FIT to GPX?
Your watch gives you a .FIT file, but maps, hiking portals, editors and blogs expect GPX. This extracts the GPS track and elevation from the FIT into a clean, standards-compliant GPX.
How to convert FIT to GPX
1. Drop your FIT file above (or click to choose). 2. It is converted on the spot. 3. Your GPX download starts automatically. No sign-up, and your file is never stored.
FAQ
What happens to my file?
Your file is sent to the Reisezoom server for processing, handled there and deleted immediately — nothing is stored. A browser cannot read FIT, TCX, KML or KMZ — some of those are packed binary formats. The conversion uses the same component as the desktop app.
Is it free, no sign-up?
Yes — completely free, no sign-up, and your file is never stored; it is only used to convert.
Which devices does it work with?
Any device that records .FIT: Garmin (Edge, Fenix, Forerunner…), Wahoo, Coros, Suunto and more.
