Heart rate, laps, and styles can be lost across formats — we say so instead of silent failure. Not a route editor.

FAQ
Is my export uploaded?
No. Archives unpack and convert in browser memory. No account required.
How is this different from FIT → GPX?
Convert archives is for account zips and multi-file batches. Pair pages are fixed one-format routes.
Can you write FIT?
No. We read FIT and output GPX / TCX / KML and similar formats.
Will a huge zip freeze my tab?
Very large exports are limited by device memory. Prefer a desktop browser and close heavy tabs.
How do I request a Strava / Garmin export?
