3D model converter
Turn OBJ files into FBX without installing anything. The target format on this page is already set to FBX, so a single file or a whole folder is one press of Convert away.

Files travel over TLS and are deleted from the server as soon as the conversion finishes.
OBJ is plain-text geometry with an .mtl sidecar for materials — universal, and very old. FBX is Autodesk's interchange format, the standard for rigged and animated assets.
Meshes, normals and UV coordinates are translated between the two scene descriptions rather than re-tessellated, so the geometry you get out is the geometry you put in. The FBX you get back keeps skeletons, skinning, animation takes and cameras, and gives up openness — the format is proprietary. Check materials and texture paths afterwards — that is where OBJ and FBX disagree most.
