FIT File Tools for Reading, Viewing, and Editing
Convert, inspect, repair, and edit activity files with tools that run on your device.
A FIT file is a compact activity file used by Garmin watches, bike computers, and many fitness apps. It can contain GPS points, timestamps, laps, elevation, heart rate, cadence, and power. A FIT file reader or viewer helps you understand what a recording contains; a converter makes the data easier to open in a spreadsheet, map, or training platform.
Choose a FIT file tool below to convert formats, recover readable points from a damaged recording, combine split activities, or edit fields in an existing file. Switchback processes activity files in your browser, so your file stays on this device. Use the FIT file reader and viewer for a quick summary, or open the FIT file editors to change activity data. For a damaged activity, follow the FIT file repair guide.
