STL to OBJ — an STL for Blender and other 3D programs
Convert STL to OBJ in your browser: shared corners joined, so the OBJ has each point once and is smaller than the STL. Several STL files become named objects in one OBJ. Nothing uploaded.
Saves model files for your slicer, never printer code. Opened and sliced in PrusaSlicer, OrcaSlicer, Bambu Studio and Cura.
About this conversion
An STL stores every triangle with its own three corners; the OBJ written here stores each point once and the faces refer to them, so programs like Blender get a connected surface they can smooth and edit, not a pile of loose triangles. Several STL files dropped together become separately named objects in one OBJ.
Just want to look inside it?
The same tool without converting anything: open the file and read it.
The same model, other ways
The model stays open after it is read, so the format is picked at the end: the same model can leave here as 3MF (.3mf) or STEP (.step). Before that you can repair it, cut it, make it smaller or combine it with another one.
Questions
- Does the OBJ get colours or textures?
- No — an STL has none to carry over. The OBJ holds the shape only.
