Drop several GPX files (or FIT, TCX, KML/KMZ, GeoJSON…) and merge them into a single GPX track. Sort the parts automatically by their timestamps or arrange them by hand with the ↑/↓ buttons, then download one file. Keep them as separate segments (no line drawn across the gaps) or join everything into one continuous segment. Plain GPX files stay in your browser; other formats are briefly sent to our server for conversion.
FAQ
What happens to my file?
GPX files are read right in your browser. Other formats (FIT, TCX, KML/KMZ, GeoJSON, NMEA) can't be read by a browser — those are sent to the Reisezoom server for conversion, processed there and deleted immediately. GPX is text and is read in the browser. Every other format has to be converted first, and only the server can do that.
Are my files uploaded?
No — GPX files are merged entirely in your browser. Other formats (FIT, TCX…) are only converted to GPX server-side and never stored.
In what order are they joined?
By timestamp when “Sort by time” is on, otherwise in the order of the list — reorder with the ↑/↓ buttons.
