4 Best Free FIT File Editor Software for Windows

Here is a list of best free FIT file editor software for Windows. Using these free software, you can view and edit FIT files. FIT i.e. Flexible and Interoperable Data Transfer is a file format developed by Garmin used to store GPS points, tracks, and routes. You can edit many other GPS track files with these software including GPX, KML, TCX, TRK, etc.

To edit FIT files, you can change waypoints or track points’ information such as latitude, longitude, altitude, name, description, symbol, etc. You can also add new track points, delete existing ones, reorder them, reverse their order, etc. These software let you create new routes and tracks too.

After editing FIT file, you can convert and save the modified version in some other file format like GPX, KML, TCX, WPT, LOC, CSV, etc.

My Favorite FIT File Editor for Windows:

Garmin BaseCamp is one of my favorite software because it is a featured software and it supports a lot of formats other than FIT, such as GPX, KML, TCX, LOC, etc. If you want a simple yet effective FIT file editor, try GPS Utility.

Also, you may checkout lists of best free TCX File Editors, GPX File Editors, and FIT File Viewers for Windows.
