AideCAD is purpose-built for this specific conversion. Unlike general file converters, it understands CAD layers, blocks, and georeferencing (if your DWG contains经纬度/UTM coordinates).

Zamzar is a veteran in file conversion. While it’s a general tool, its DWG→KML engine handles 2D geometry well. Note: It does handle 3D extrusion or complex blocks perfectly. AideCAD is purpose-built for this specific conversion
Pick one of the free links above, upload your CAD file, and see your floor plan or site map floating accurately over real satellite imagery in Google Earth, all in under 60 seconds. Disclaimer: Free online converters change their terms periodically. If a link is no longer free, try the next one on the list. For sensitive or proprietary DWG files, always use offline software like QGIS to avoid data privacy risks. While it’s a general tool, its DWG→KML engine
MyGeodata is a specialized GIS cloud converter. It reads DWG’s internal coordinate system (if defined) and reprojects it to WGS84 (the standard for KML/Google Earth).
