(Note: Always check for “MyGeodata Converter” if the link changes. It is the industry standard for free cloud conversions.)
Let’s walk through a practical example using AideCAD (the most reliable free link).
Step 1: Prepare your DWG file.
Step 2: Visit the free link.
Go to https://www.aidecad.com/en/dwg-to-kml/
Step 3: Upload and configure.
Step 4: Convert. Click “Convert to KML.” Wait 10–60 seconds.
Step 5: Download and test.
Cause: The converter simplified arcs to straight segments.
Solution: Use a tool that retains splines (try MyGeodata instead of Zamzar). Or, in AutoCAD, use PE (Pedit) to convert splines to polylines with a high resolution.
Before you upload, ask yourself: Does my DWG have real-world coordinates?
The keyword "dwg to kml online converter free link" implies a one-off conversion. But if you have 100 DWG files to convert, no genuinely free online link exists for batch jobs (servers cost money).
For batch jobs, use the free desktop alternative again: QGIS with the Processing Toolbox → Batch Processing → Convert format to KML.
Alternatively, if you want a single free link for small batch files (max 3 files at once), try aconvert.com (search for their DWG to KML tool). It allows 3 simultaneous uploads but adds a subtle footer to the KML.

Zamzar is the most reliable free online converter. It handles both 2D and 3D DWG files (versions up to AutoCAD 2024).
