Alternatives to Fit File Tools
If the requirement is “do not send the activity to someone else’s server,” Switchback is built for that.
People search “Fit File Tools alternative” when they want the same FIT jobs without sending the activity to a third party, or when a specific export is missing.
Switchback is the local option: convert and edit FIT, GPX and TCX in the browser. Gotoes is the other common upload-based toolbox, with Strava and Garmin connections Fit File Tools and Switchback do not try to replace.

Questions
Is Switchback a clone of Fit File Tools?
No. Several jobs overlap (time, combine, strip, convert). Switchback runs entirely in the browser. Fit File Tools processes on their server.
What about Gotoes?
Gotoes is another upload-based toolbox, with Strava/Garmin connections. See Switchback vs Gotoes for the table.
Will my power data survive?
When the source FIT recorded power, Switchback keeps it in FIT edits and in GPX/TCX exports that use the Garmin extensions.
Do I need to sign in?
No. There is no Switchback account.
