Our free and fast tool will convert most IGS (Initial Graphics Exchange Specification) CAD files to a standard OBJ (Wavefront) 3D model file that can then be edited further in most popular 3D editing packages such as Blender or 3D printed without any further processing. Our conversion tool can also batch convert multiple IGS files; up to 25 files at a time can be converted.
To convert your IGS file, click the Upload button above and select the file to convert. Once selected, the file will be converted to a OBJ file and will be ready for download shortly afterwards. For more information about the IGS to OBJ conversion process, see the conversion information section below.

IGS is an open file format used within CAD applications as a means of saving data in a format that can be opened and edited in other CAD applications. Its roots can be traced back to the mid-1970s, when it was used by the United States Air Force.
The format itself is a human-readable text-based format and contains data that can represent many different CAD elements, such as points, lines, arcs, and much more. IGS files can be opened with many modern CAD applications, such as FreeCAD.

The OBJ file format, originally created by Wavefront Technologies and later adopted by many other 3D software vendors, is a simple text-based file format for describing 3D models/geometry. This data can include vertices, faces, normals, texture coordinates, and references to external texture files.
As the format is text-based, it is relatively straightforward to parse in 3D modeling applications. A downside of the text-based format is that the files can be rather large compared to similar binary formats such as STL and compressed files such as 3MF.
Our tool will save any material and texture files separately; these additional files will be included with your final OBJ file at the time of download.
Yes! If your IGS file contains textured geometry, the texture image files along with the texture coordinates (UV data) will be exported with the final OBJ file.
We aim to process all IGS to OBJ conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.
We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features and improvements being added every week.
Yes, of course! We do not store the IGS file you submit to us. The resulting OBJ file, once created is deleted 15 minutes after upload and the download link will expire after this time.
No. All our conversion tools process your IGS file on our dedicated conversion servers, meaning you can use our tools on low-spec computers, laptops, tablets, and mobile devices and receive your converted OBJ file quickly.
Yes! Our IGS to OBJ tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.
Yes. Although you can use an Ad Blocker, if you like our IGS conversion tool please consider white-listing our site. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.
Yes. When you have converted your IGS to OBJ, there is a "Feedback" option that you can use to let us know of any issues you encountered when converting your file.
