What is a FIT File Editor?
A FIT file editor allows you to modify the data stored in .fit files from your fitness devices. Unlike simple viewers, editors let you change activity metadata, trim recordings, adjust GPS coordinates, and modify workout metrics before re-exporting the file.
What can I edit?
You can modify activity type (running, cycling, etc.), start time, total distance and time, individual data points like heart rate and power, and apply GPS coordinate offsets to fix drift issues.
Is my data safe?
Absolutely. All editing is done locally in your browser. Your FIT files are never uploaded to any server. Your original file remains unchanged until you download the edited version.
Your Privacy is Protected
Your FIT files are processed entirely in your browser. No data is ever uploaded to our servers. Your workout data, GPS locations, and health metrics stay on your device.
