What is a KML file?

KML (Keyhole Markup Language) is an XML-based format used for representing geographic data in Earth browsers like Google Earth. It describes placemarks, paths, polygons, and other geospatial elements.

KML is widely used in mapping, environmental research, and tourism to display annotated geographic locations. Files can be extended with images, 3D models, and time-based data.

How to open KML files

KML files can be opened with Google Earth, Google Maps, and various GIS software such as QGIS. They are used for geographic data visualization.

Convert KML to GPX, KMZ, or CSV using AnyConv or GIS tools for use across mapping platforms.
