What split modes are available?

Three: every N points (fixed-size chunks), by time gap (start a new part whenever the gap between two points exceeds your threshold), and by date (a new part per calendar day in the timestamps).

Does time-gap or date splitting need timestamps?

Yes. Those two modes read the time element on each track point. If your file has no timestamps, use the every-N-points mode instead.

Are the output files valid GPX?

Yes. Each part is wrapped in a complete GPX 1.1 document with a single track and segment, so every piece opens in any GPX-aware app on its own.

Is my track uploaded?

No. The file is parsed and split entirely in your browser using the built-in XML parser — your GPS data never leaves your device.

What happens to elevation and time on each point?

Each track point is copied verbatim, including its ele and time children, so no elevation or timing information is lost in the split.

GPX Splitter — Gera Tools

Split a GPX file in your browser

This tool breaks one large GPX track into several smaller GPX files. It is built for anyone whose device recorded a multi-day trip or a very long ride as a single file and now wants it cut into manageable, per-day or fixed-size pieces.

How it works

The GPX is parsed with the browser’s DOMParser, and all track points are collected in order. Then one of three rules is applied:

Every N points — the list is chopped into fixed-size chunks of N points each.
By time gap — a new part begins whenever the time between two consecutive points exceeds your threshold in minutes, which neatly separates recordings paused overnight.
By date — a new part begins whenever the calendar day of a point’s timestamp changes, giving you one file per day.

Each resulting group of points is wrapped in a complete, standalone GPX 1.1 document.

Notes

Everything runs locally — nothing is uploaded. Time-gap and date modes need timestamps on the points; if yours has none, the every-N-points mode always works. To recombine parts later, use the GPX Merger.
