KML and GPX Compared:
When to Use Each Format
What is a GPX file?
A GPX (GPS Exchange Format) file is a widely used, open-standard XML format specifically designed for storing and sharing GPS data. It serves as a universal language for route planning and navigation, allowing users to capture essential geographic information such as waypoints, tracks, and routes in a consistent, device-agnostic format. Whether you’re recording a mountain bike trail, planning a multi-day hiking expedition, or analyzing a running route, GPX files make it easy to store, share, and visualize your journey across a wide range of platforms and devices.
Originally developed to promote interoperability between GPS hardware and mapping software, GPX has become the go-to format for outdoor enthusiasts, athletes, and professionals alike. It's fully supported by popular fitness and navigation apps such as Garmin, Strava, Komoot, AllTrails, Gaia GPS, and many others. Most GPS-enabled devices and smartphones can import and export GPX files, making them an ideal choice for syncing routes between your computer, watch, bike computer, or mobile app.
What is a KML file?
A KML (Keyhole Markup Language) file is a powerful, XML-based format designed to store and share rich geographic information—everything from detailed routes and waypoints to custom pins, paths, polygons, and even 3D models. Originally developed by Google for use in Google Earth and Google Maps, KML has become an industry-standard for visualizing spatial data on top of satellite imagery, street maps, and terrain models. Whether you’re plotting a multi-day hiking trail, mapping out a sales territory, or embedding interactive location-based content on your website, KML makes it easy to package all the necessary coordinates, styling details, and metadata in a single, portable file.
Unlike simple GPS coordinate lists, a KML file gives you full control over how each element appears—choose custom icons and colors, define altitude and tilt for 3D fly-throughs, group waypoints into folders, and even attach descriptive pop-up balloons with images, links, and formatted text. Because KML is based on open XML standards, it can be edited with any text editor or specialized GIS software, and it’s compatible with a wide range of mapping platforms beyond Google’s ecosystem, including ArcGIS, QGIS, and mobile GIS apps. With a KML file in hand, you can effortlessly overlay your routes and points of interest onto interactive maps, share them with collaborators, or embed dynamic, location-aware visualizations directly into your website or mobile app.
