How It Works

reaConverter offers the fastest, simplest solution for converting your GMT files into DWG without GIS software - all files processed on your PC for maximum privacy and speed.

Technical note

GMT to DWG: what carries over and what does not

Geospatial coordinates are absolute positions on the earth, and they are large: a projected easting runs to six or seven digits, while latitude and longitude are small decimals. DWG expects a drawing laid out near its own origin in millimetres or inches. The geometry itself converts correctly, but it can land tens of kilometres from 0,0, or arrive at a scale where an entire county is forty units across. Zoom to extents first, then measure one known distance before dimensioning anything.

Map Data Workflow

From map data to a working drawing

Converting GMT to DWG usually means handing GIS data to someone who works in CAD. reaConverter makes that hand-off without a GIS seat on either side, for one layer or a whole delivery.

  • Convert every layer in a folder to DWG with the same settings
  • Go the other way too, from DWG to Shapefile, when the GIS team needs the drawings back
  • Render the same data to PDF for a quick review copy
  • Pick up new data automatically with Watch Folders, or script the job from the command line

Everything runs on your PC, which matters for cadastral, utility and client data that should not pass through an upload form.

When I switched from Mac to Windows, I couldn't open my old DWG files. reaConverter saved me – it converted them all to PDF and JPG with perfect scaling. Now I can view my CAD portfolio on any device. Thank you for making cross‑platform work possible!

I typically avoid installing too many programs to keep my hard drive clutter-free, but constantly uploading/downloading files for conversion became too time-consuming. That's why I chose reaConverter when I needed to transform DWG files into readable PDFs—and it performs flawlessly!

My son is training to become an architect, so he's learning Autodesk, AutoCAD, and other design software. With so many file formats in this field, we needed a reliable conversion tool fast. reaConverter was the perfect solution - lightning-fast conversions, zero lag, and it works completely offline!

I needed to convert DWG to DXF for a laser cutter, and reaConverter did it flawlessly. The geometry remained intact, and the line weights were preserved. I've tried free tools, but they always mess up arcs. This is the only one I trust.

After nearly two years of relying on online converters, I finally installed standalone software. Why didn't I do this sooner? Now I can work completely offline — no more wasted time uploading/downloading or eating through my data allowance!
