Frequently asked questions
Is my TCX file uploaded?
No. The file is read by your browser and shown on your own device. Nothing is sent to a server, and it is gone when you close the tab.
How do I open a TCX file without installing software?
Drop the .tcx file on this page. It opens straight away in the GPX & GeoJSON Viewer, on Windows, macOS, Linux, Android and iPhone alike.
What if my TCX file doesn't open?
The viewer checks the file's content, not just its name. If it is damaged or not really a TCX file, you'll see an error or can switch to the hex view to look at the raw bytes.
