Common Questions

Will I lose any important data?

Core GPS data (coordinates, elevation, timestamps) is fully preserved. Sensor data like heart rate and power is included via GPX extensions, but not all apps read these. For full sensor data preservation, consider keeping the original FIT file or converting to TCX.

Can I convert multiple FIT files at once?

Our converter processes one file at a time for optimal accuracy. For multiple files, convert each separately—each conversion takes only seconds.

Does the file size change?

GPX files are typically 2-3x larger than FIT files because GPX uses text (XML) while FIT uses binary encoding. This doesn't affect functionality.

What if my FIT file has no GPS data?

Indoor activities (treadmill, stationary bike) without GPS will result in a minimal GPX file. GPX is GPS-focused, so it's best suited for outdoor activities with location data.

Can I edit the GPX file after conversion?

Yes! GPX files are human-readable XML. You can:

  • Open in any text editor to modify
  • Use GPX editing software
  • Remove start/end points for privacy
  • Split or merge tracks
