GPS & Fitness Converter Tools
Convert GPS tracks, routes, and waypoints between formats. Import data from Garmin devices, prepare files for Google Earth, and export to spreadsheets for analysis.
Understanding GPS File Formats
GPX (GPS Exchange Format) is the universal XML-based standard for GPS data. It stores waypoints, tracks, and routes with latitude, longitude, elevation, and timestamps. Most GPS devices and apps including Garmin, Suunto, and AllTrails support GPX export.
KML (Keyhole Markup Language) is Google Earth's native format. It supports rich geographic visualizations including placemarks, paths, polygons, and 3D models. Converting GPX to KML lets you view your outdoor activities on Google Earth's 3D globe.
FIT is Garmin's proprietary activity file format. It contains detailed fitness data including heart rate, cadence, power, and temperature alongside GPS coordinates. FIT files are created by Garmin watches, Edge cycling computers, and other fitness devices.
Common GPS Conversion Workflows
Hikers and cyclists often record activities on a Garmin watch (FIT format), convert to GPX for sharing on AllTrails or Strava, then convert to KML for visualization in Google Earth. CSV conversion is useful for analyzing elevation profiles, speed data, and waypoint coordinates in Excel.
