Combine KML Features into Multipart
Upload a KML file with multiple features. This tool groups them into a single multipart feature — no geometry is merged or modified.
What this tool does
Merges all separate features into a single multipart feature. For example, 5 individual Polygon features become 1 MultiPolygon feature. The geometries are grouped — not dissolved or unioned. The output file will contain exactly one feature.
Powered by GDAL WebAssembly and Turf.js. Features are grouped into multipart geometry — not dissolved or unioned.
KML is best when the combined multipart feature will be shared in Google Earth — all geometries render as a single placemark overlay.
