STL to OBJ converter

STL is a dead end for editing: no UV, no material, no groups, and a duplicated vertex for every triangle corner. Converting to OBJ produces a file that editors and renderers are happy to work with.

When people need this

Usually a printable model that now has to be rendered, textured or dropped into a scene. Also the first step when a downloaded STL needs retopology or a UV unwrap.

What to check in the result

Nothing appears out of nowhere. The result has no texture and no UV layout because the source never had any — you get clean geometry to work from, not a finished asset.
