What changes when exporting OBJ as STL?

An OBJ source is useful for 3D editing and interchange with older modeling software. OBJ primarily describes geometry as vertices, texture coordinates and faces, often with separate MTL files for materials.

The STL result is intended for 3D printing and simple mesh export. STL records triangle geometry rather than colors, UV maps, materials, or rigging, so it suits print meshes rather than complete scenes.

Before you download

  • The converter operates on supported mesh geometry. Do not assume it preserves original materials, UV textures, skeletal animation or full scene hierarchy.
  • Check mesh units, face orientation and scale in your target application, especially before printing or importing into a game engine.

About this tool

Convert embedded triangle geometry from OBJ to STL.

Geometry only. Textures, materials, rigging and animation are not preserved; complex polygons are triangulated. glTF imports require embedded (not external) buffers and non-interleaved triangle accessors.
