Introduction: Why Convert KML to MBTiles? At first glance, the request to "convert KML to MBTiles" seems like a cartographic paradox. KML (Keyhole Markup Language) is an XML-based format for describing vector features—points, lines, polygons, and 3D models. MBTiles, on the other hand, is a SQLite database containing millions of pre-rendered raster image tiles (or, in modern extensions, vector tiles).
You cannot simply change a file extension from .kml to .mbtiles . Instead, the conversion is a process : you are taking the geographic data contained in a KML file and it into a zoomable tile pyramid. convert kml to mbtiles

QGIS is free, open-source, and handles the entire pipeline. MBTiles, on the other hand, is a SQLite
If you need (so users can click features), use Python to convert KML to GeoJSON, then to MVT (Mapbox Vector Tiles).

GDAL is the "Swiss Army knife" of geospatial data. While it doesn't convert KML to MBTiles directly, it converts KML to GeoTIFF, then to MBTiles.
