When people need this
Most often a model bought or downloaded as OBJ that now has to be printed. Also common after sculpting in ZBrush or Blender, where OBJ is the habitual export and the slicer refuses it.
OBJ to STL converter
OBJ carries more than a printer needs: UV coordinates, material references, sometimes several named objects. STL keeps the shape and throws the rest away — which is exactly what a slicer wants.

Separate objects inside the OBJ merge into one mesh. If the model was made of parts you intended to print separately, split it before converting rather than after.
