GPX to KML Converter

About this tool

Paste GPX XML and get a KML 2.2 document that opens in Google Earth and other KML-aware viewers. Tracks and routes become LineString placemarks, waypoints become Point placemarks, and the converter keeps useful metadata such as names, descriptions, timestamps, and elevation when those fields are present.

Use the styling controls to set the track/route line color, line width, line opacity, and waypoint icon color before exporting. The altitude mode controls how Google Earth interprets elevation values: clamp to ground for normal map overlays, absolute for 3D paths with sea-level altitude, or relative to ground for heights above terrain.

Worked example

Input:

<gpx version="1.1">
  <metadata><name>Trip</name></metadata>
  <trk><name>Morning Run</name><trkseg>
    <trkpt lat="52.100" lon="5.100"><ele>10</ele></trkpt>
    <trkpt lat="52.101" lon="5.102"><ele>12</ele></trkpt>
  </trkseg></trk>
</gpx>

With the default red line, width 4, 80% opacity, and clamp-to-ground altitude mode, the output includes a KML <Document> named Trip, a shared <LineStyle> color of cc4444ef, and a <LineString> with coordinates 5.1,52.1,10 5.102,52.101,12.

Limits and edge cases

• The tool converts one GPX document at a time and returns plain KML text, not KMZ zip files.
• It reads standard <trk>, <rte>, and <wpt> elements. Vendor extension data is ignored so the output stays portable.
• KML colors use aabbggrr byte order; this tool converts from familiar CSS #RRGGBB and #RGB inputs for you.
• Empty documents or GPX files with no track, route, or waypoint return a clear error instead of an empty KML file.
