See how we test, rate, and review products on TechRadar. The aim was to push each software platform to see whether it could simply and easily not just convert a range of content types but also do so faithfully and consistently without introducing errors. We then tested the service using a handful of files to see how the software could be used for converting different file formats. To test for the best 3D file converter we first set up an account with the relevant software platform, whether as a download or as an online service. Uploads and downloads are relatively speedy, although the limit of 50 MB for uploads can be problematic if you have large 3D files. Helpfully, if your model is split into multiple files, the batch upload can be used to provide Greentoken with all the necessary files at once. The online interface does support batch conversion, but you can only upload a maximum of five files at a time. Notably, though, conversion to 3DP is not supported by Greentoken. You can convert files to STL, STLB, COLLADA, OBJ, 3DS, PLY, JSON, and X. What’s particularly nice about it is that it also supports a wider variety of outputs than other free tools. The platform can handle any of 52 3D file format inputs, including all of the most popular proprietary and neutral formats.

Greentoken offers an impressive range of file support for a free online tool.
