Decide whether you need one file or one track
“Merge GPX files” can mean two things: put several independent tracks in one file, or replace them with one track containing their segments. Float GPX Editor supports both. Neither operation calculates a connecting road between recordings.
| Goal | Action | Result |
|---|---|---|
| One GPX, separate tracks | Export All content or selected objects | One file with several independent tracks |
| One track, original segments | Merge tracks, then export the result | One file containing the merged track and its segment gaps |
Import and inspect the source GPX files
Click “Import GPX” and select your files together, or drag them onto the page. Each can be up to 10 MiB; together they must fit the 100,000-point project limit. Select each track by name and fit it to view to check its direction and endpoints.
Route objects must use “Convert to track” before merging. Waypoints remain independent. Keep the original files or make a project duplicate so you can compare the result.
Select, order and merge the tracks
Merge order is the order you explicitly choose, not an automatic sort by timestamp or location. If one recording runs backward relative to the intended sequence, reverse it before merging, remembering that original timestamps will stay attached.
- Use the checkboxes next to at least two tracks. Clicking names alone only changes the current selection.
- Open “Merge tracks”. Move tracks up or down to set the sequence and enter the resulting name.
- Confirm the merge. The chosen tracks are replaced by a single track with the original segments in that order.
- Inspect the result on the map and in Data. Undo once to restore the source tracks if necessary.
Understand the gaps, time and preserved metadata
The last point of one source segment and first point of the next are not joined. Distance is summed within segments. Duration also excludes gaps between segments, so it may differ from the total clock span between the earliest and latest reading.
Original point times, elevations and extensions stay with retained points. The merge preserves source track metadata in application extensions; source file metadata and waypoints are not deleted. Destination apps may interpret or display segments and extensions differently, so inspect the file there too.
Export only the intended result
For just the merged track, clear previous checkboxes, select the result and export “Selected”. For all objects, including standalone waypoints, choose All content. Map visibility does not filter either scope. Combined export writes GPX 1.1.
Wait for preparation and click “Download GPX”. Reimport the download to check that the expected number of tracks and segments is present. If you only wanted several tracks in one file, skip the merge and export those original objects together.
