Free Link: https://www.zamzar.com/convert/dwg-to-kml/
Free Tier Limits: 50MB per file, but only 2 free conversions per day. No account required.
Why it’s useful: Zamzar is the oldest online file converter. It works best for simple DWG files that are already georeferenced correctly. It ignores complex CAD entities (blocks, hatches) but converts polylines and points flawlessly.
How to use it:
Pros: No signup, large file limit (50MB), email delivery works reliably.
Cons: Only 2 files per day; poor handling of custom coordinate systems; you must pre-convert your DWG to WGS84 in AutoCAD first.
Before you upload, ask yourself: Does my DWG have real-world coordinates?
No single online tool perfectly converts all DWG files to KML because CAD drawings and GIS maps are fundamentally different. But the three converters above give you the best chance of success – without spending a dime. dwg to kml online converter free link

Converting DWG to KML online for free has never been easier. The links provided above are safe, tested, and ready to use. Remember: the quality of your output KML depends 80% on the quality of your input DWG. Clean your file, check your coordinates, and choose the right converter for your specific needs.
Next step: 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. Free Link: https://www
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.
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. Pros: No signup, large file limit (50MB), email
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.
