STL and OBJ are the commonly used formats for 3D printing. How to convert STL to OBJ and vice versa? In this post, you will know how to convert STL to OBJ or OBJ to STL on different platforms.

What is STL? What is OBJ? According to Wikipedia, STL is a file format native to the stereolithography CAD software developed by 3D Systems. OBJ is a geometry definition file format developed by Wavefront Technologies. Most CAD software and 3D printing software supports STL and OBJ format.

Sometimes, you may need to convert STL to OBJ, try the below 3D converters. (To convert videos, you can use the best free video converter – MiniTool Video Converter.)
