GPX Splitter

What this tool does

Paste a GPX track and split it into smaller segments. Choose distance to cut after a target length, time to cut after an elapsed duration, or stops to start a new segment when there is a large timestamp gap between points. The tool can output a fresh GPX document with one track per segment, or a text summary of distance, duration, and point counts.

Everything runs locally in WebAssembly. No map service or upload is required.

Worked example

With mode=stops, stop_gap_s=120, and output=summary, a track with a 20-minute pause produces two segments:

Split into 2 segments (stops, on gaps over 120 s).

Segment 1: 0.11 km (0.07 mi), 2 points, 0:01:00  [2024-01-01T00:00:00Z → 2024-01-01T00:01:00Z]
Segment 2: 0.11 km (0.07 mi), 2 points, 0:01:00  [2024-01-01T00:21:00Z → 2024-01-01T00:22:00Z]

Switch output to gpx when you want a copyable GPX file with tracks named Original name - Part 1, Original name - Part 2, and so on.

Limits and edge cases

• Time and stop modes require parseable GPX <time> values on track points.
• Distances use great-circle haversine distance between consecutive points.
• Distance/time splits duplicate the boundary point so segments remain geometrically contiguous; stop splits leave the real recording gap.
• The output preserves latitude, longitude, elevation, and timestamp values, but GPX extensions such as heart rate, cadence, or power are not retained.
• This is deterministic text processing; there is no interactive map preview or click-to-split UI.
