A FIT (Flexible and Interoperable Data Transfer) file is a binary file format used by Garmin devices to store fitness data including GPS coordinates, heart rate, cadence, and other metrics.

GPX (GPS Exchange Format) is a widely supported format that can be used with many different apps and devices. Converting to GPX makes your workout data more accessible and shareable.

Will I lose any data during conversion?

The converter preserves all essential GPS data and basic metrics. However, some device-specific data might not be included in the GPX format as it has a different structure than FIT files.

Can I upload the converted GPX file to Strava?

Yes! The converted GPX file can be uploaded to Strava, Komoot, RideWithGPS, and most other fitness platforms that accept GPS data. GPX is one of the most universally supported formats.

How do I view a GPX file after conversion?

GPX files can be viewed in many apps including Google Earth, Strava, Komoot, or free tools like GPXSee and GPS Visualizer. Most mapping applications support GPX import.

What is the difference between FIT and GPX formats?

FIT is a binary format optimized for Garmin devices with native sensor support, while GPX is a text-based XML format designed for universal GPS data exchange. FIT files are smaller but GPX files work with more applications.

Can I convert multiple FIT files to GPX at once?

Yes, our converter supports bulk processing. You can upload multiple FIT files and convert them all to GPX simultaneously, making it easy to batch convert your workout library.

I'm a software developer and sports enthusiast. I created these converters to help athletes manage their workout data efficiently.

Our FIT to GPX Converter extracts GPS coordinates, elevation, and heart rate from your Garmin FIT file and saves them as a standard GPX file — ready to upload to Strava, Komoot, RideWithGPS, or any mapping app. All processing happens in your browser; your file is never sent to a server.

What Data Is Preserved in the GPX File?

GPX is a GPS-focused format. Core location data is fully preserved; some device-specific metrics are not part of the standard GPX specification.
