STL to OBJ Converter
Convert embedded triangle geometry from STL to OBJ.
What changes when exporting STL as OBJ?
An STL source is useful for 3D printing and simple mesh export. STL stores a triangle surface without UV textures or scene hierarchy; it is widely used for 3D printing.
The OBJ result is intended for 3D editing and interchange with older modeling software. OBJ is widely imported by 3D authoring applications, but its external materials and textures need separate handling.
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 STL to OBJ.
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.
