I want to convert a .cgm file to an image file (.png) on windows.

Are there any freeware/opensource tools for this? I tried to ImageMagik but it does not support this operation. Commandline inteface will be an added advance if any of the tools provide it.

UniConvertor is open source, and the best choice in my opinion.

The windows binaries worked great for me, https://sk1project.net/uc2/download/

From a command line you'd simply type uniconvertor input.cgm output.png

You can try https://cortona3d.com/en/cortona2d-viewer-download. When installed it understand .cgm extension and directly opens in IE and you can view it/or take snapshot.

Other tool that you can try(but not free) is reaConverter(https://www.reaconverter.com/) It has a nice command line interface that converts cgm to PNG directly

  • Huh, i was looking for some opensource/Freeware. I tried cortona2d-viewer It works fine. reaConverter requires license so i am avoiding it. – Goutam Lavudiya Jul 04 '19 at 05:07

There is a free tool available XnView which is very handy when it comes to view, resize and edit your images. It supports more than 500 different formats. But you will have to download an additional plug-in https://www.cadsofttools.com/products/plugins-for-3d-party-programs/ It will enable your need to deal with CGM file formats.
