The biggest hurdle in this conversion is Coordinate Reference Systems (CRS).
AutoCAD DWG files usually rely on local coordinate systems (e.g., 0,0 as the building corner) or projected systems like UTM (Universal Transverse Mercator). KML strictly uses WGS84 (EPSG:4326)—geographic coordinates (latitude/longitude).
If your DWG file isn't already georeferenced (assigned real-world coordinates), any free online converter will produce a KML that appears miles away from its true location or doesn't appear at all. dwg to kml online converter free link
In the world of architecture, urban planning, and GIS (Geographic Information Systems), the need to bridge the gap between design software and mapping software is constant. Architects design in CAD (using .dwg files), while planners and clients visualize data in Google Earth (using .kml files).
If you are looking for a "DWG to KML online converter free link," you have likely discovered that this is not always a straightforward process. Because DWG is a proprietary format owned by Autodesk, true "free" online converters are rare. The biggest hurdle in this conversion is Coordinate
This article explains the best methods to convert these files for free, provides working links, and offers a step-by-step guide to ensure your data lands in the right location.

If you’ve ever tried to send a standard AutoCAD DWG file into Google Earth, you know the struggle. DWG files live in flat, mathematical coordinate spaces (like State Plane or UTM). KML files live on a curved globe (WGS84 Lat/Long).
You cannot simply “rename” the file. You need a geospatial translator.
Most engineers assume this requires expensive software like ArcGIS or AutoCAD Map 3D. That is no longer true.
Today, I am sharing a direct link to a free, online DWG to KML converter that works entirely in your browser—no credit card, no email signup, and no 500MB software download.
