KML files often contain bloated descriptions, HTML formatting, or metadata within their tags. Clean up your data attributes prior to conversion to reduce the footprint of vector MBTiles.

QGIS is the "Swiss Army Knife" of GIS and offers the most robust path for this conversion. Import the KML Open QGIS and go to Layer > Add Layer > Add Vector Layer Browse for your file and add it to your canvas. Add a Basemap (Optional)

MBTiles stores data as pre-rendered image tiles (raster) or compressed vector tiles. The rendering engine only loads the specific tiles needed for the current viewport and zoom level.

--drop-fraction-as-needed : Automatically simplifies features at lower zoom levels to keep the file size highly optimized. Method 3: Direct Conversion via Online GIS Tools
Converting KML to MBTiles: A Deep Dive for Modern Web Mapping
MBTiles is a specification created by MapBox for storing tiled map data in a single SQLite database file. It can store (PNG/JPEG images) or Vector Tiles (encoded map data).
