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 KML?
KML (Keyhole Markup Language) is Google's format for geographic data — the format Google Earth and Google My Maps read.
Why convert FIT to KML?
Go straight from a Garmin/Wahoo .FIT to KML for Google Earth — no GPX detour. Your recorded activity, ready to view in Google's tools.
How to convert FIT to KML
1. Drop your FIT file above (or click to choose). 2. It is converted on the spot. 3. Your KML 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.
Do I need to make a GPX first?
No — drop the FIT straight in and get KML directly.
