About

GML

GML (Geography Markup Language) is an XML-based geospatial data encoding standard defined by the Open Geospatial Consortium (OGC). GML provides rich geospatial data modeling capabilities, supporting complex geometry types, topology, coordinate reference systems, and spatiotemporal data. GML is widely used in European and government sectors, often for national spatial data infrastructures (SDI).

GPX

GPX (GPS Exchange Format) is an XML-based GPS data exchange format and the de facto standard for exchanging data between GPS devices and applications. GPX supports three core data types: Waypoints (single location points), Routes (ordered path point sequences), and Tracks (GPS-recorded point sequences with timestamps). GPX files can be generated by various GPS devices, sports watches, and mobile apps.

Conversion trade-offs

GML: limitations to know

  • Complex format, large files, high parsing overhead
  • Limited interoperability between different GML application schemas
  • Limited web application support, not suitable for online maps

GPX: what you gain

  • Supported by almost all GPS devices and apps for import/export
  • Human-readable, allows manual editing of routes and waypoints

Why convert GML to GPX?

Converting GML to GPX is one of the most common workflows in GIS. GML data usually comes from desktop GIS software, government open-data portals, or data exchange with partners, while GPX is what modern tools, web maps, and platforms expect. This converter bridges the two: it reads your GML files, keeps geometry and attributes intact, and writes clean GPX output — entirely in your browser, so your data never leaves your device.

Frequently asked questions

Are my files uploaded to a server?

No. The conversion runs entirely in your browser using WebAssembly — your files never leave your device.

Is the GML to GPX converter free?

Yes, completely free with no sign-up and no usage limits.

Are coordinate systems preserved when converting GML to GPX?

By default the output keeps the source coordinate system. If your GML file uses a projected CRS (like UTM), you can search any EPSG coordinate system by keyword or code and reproject in one step. Note: output formats that require WGS84 by specification (KML, KMZ, GPX) always reproject to WGS84 automatically.

Can I convert multiple files at once?

Yes — drop several GML files at once and each one produces its own GPX output.

Key Features

  • De facto standard format for GPS device data exchange
  • Supports three data types: waypoints, routes, and tracks
  • XML-based format with clear structure

Common Use Cases

  • Recording and sharing outdoor activity tracks (hiking, cycling, running)
  • Data transfer between GPS devices and mapping applications
  • Travel route planning and waypoint management

How to Use

  1. 1

    Upload your GML file — drag and drop it onto the page, or browse from your device. You can add several files at once for batch conversion.

  2. 2

    The conversion runs automatically in your browser. No upload, no server — your data stays on your device the entire time.

  3. 3

    Download the GPX file. Each input produces its own output, ready to use in your GIS, web map, or archive.
