Edit Metadata
Change sport type, start time, and activity name. Fix incorrectly labeled activities before importing into your training platform.
Trim Activities
Remove unwanted portions from the start or end of your activity. Great for cutting out warm-ups, cool-downs, or accidental recording.
Adjust GPS
Apply GPS coordinate offsets to fix shifted tracks. Useful when activities look displaced due to device or map projection issues.
What is a TCX File Editor?
A TCX file editor allows you to modify the data stored in .tcx workout files. You can update metadata, trim recordings, adjust GPS coordinates, and edit trackpoint values before exporting the edited TCX for upload elsewhere.
Is my data safe?
Yes. Everything runs locally in your browser. Your TCX file is never uploaded to any server. Your original file remains unchanged until you download the edited version.
What can I edit?
You can change sport type and start time, crop the activity timeline, adjust GPS, and edit metrics like heart rate, cadence, speed, elevation, and power (when present).
Your Privacy is Protected
