KML Viewer

Placemarks, lines and polygons are rendered with their names and descriptions. The file stays on your machine.

How to use it

  1. Drop a .kml or .kmz file on the box, or choose one.
  2. Click a placemark on the map or in the list to read its name, description and extended data.
  3. Toggle points, lines and polygons with the chips above the stats.
  4. Convert the file to GeoJSON or GPX with one click.

How it works

KML is parsed with the browser's XML parser: Placemark names, descriptions, ExtendedData, folders and Point, LineString, Polygon, MultiGeometry and gx:Track geometries. KMZ files are unzipped in the browser and the doc.kml inside is read. A placemark with broken coordinates is reported by name and skipped; the rest still draws.

Styles, icons, ground overlays, network links and 3D extrusions are not rendered; everything is drawn in one colour. Files are limited to 8 MB.

Questions

Why do my custom icons and colours not show?
The viewer reads geometry and text only. KML styling is not applied, so all features draw in the site accent colour.
Does it support KMZ?
Yes. A KMZ is a ZIP holding a KML; it is unzipped in the browser. Images packed inside the KMZ are not shown.
Can I convert KML to GPX?
Yes. Placemarks become waypoints and paths become tracks. Polygons have no GPX equivalent and are left out of that export.
