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.
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).
Converting GPX to GML is one of the most common workflows in GIS. GPX data usually comes from desktop GIS software, government open-data portals, or data exchange with partners, while GML is what modern tools, web maps, and platforms expect. This converter bridges the two: it reads your GPX files, keeps geometry and attributes intact, and writes clean GML output — entirely in your browser, so your data never leaves your device.
No. The conversion runs entirely in your browser using WebAssembly — your files never leave your device.
Yes, completely free with no sign-up and no usage limits.
By default the output keeps the source coordinate system. If your GPX 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.
Yes — drop several GPX files at once and each one produces its own GML output.
Upload your GPX file — drag and drop it onto the page, or browse from your device. You can add several files at once for batch conversion.
The conversion runs automatically in your browser. No upload, no server — your data stays on your device the entire time.
Download the GML file. Each input produces its own output, ready to use in your GIS, web map, or archive.
