When you need this

You have an STL from a 3D printing library (Thingiverse, Printables) and need to bring it into a modeling tool that expects OBJ, or a pipeline that wants named vertex/UV data instead of a bare triangle soup.

STL to OBJ — FAQ

Will this add UVs or materials that weren’t in the STL?

No — STL never stored them, so there’s nothing to recover. The OBJ output is geometry-only, same as the source.

Binary or ASCII STL — does it matter?

Both are accepted; the converter detects the format automatically.
