Free converter, no upload, no account, no file-size games.
Monsoon Cycles, Colorado Springs · Updated August 21, 2026
Choose a .fit file, get a .tcx file, done. The conversion runs entirely in your browser; nothing is uploaded anywhere, so it works on a plane and your ride data stays yours. No account, no watermark, no three-conversions-per-day meter.
Why this exists: half the online converters are upload-your-file-to-our-server services wrapped in ads. This one is a static page from a bike shop that already had the code, because the game exports rides for Strava as TCX.
