OBJ to STL Converter

Convert OBJ files into STL geometry for 3D printing and mesh workflows. The conversion keeps the model shape and removes material information.

How to convert OBJ to STL

A compact workflow for turning obj files into STL geometry for printing, slicing, and mesh editing.

01Upload an OBJ file.

02Preview the mesh.

03Center or scale the model if needed.

04Convert OBJ geometry to STL.

05Download the STL file.

The first version focuses on the conversion surface users expect: upload, tune, preview, and download.

OBJ is a common model format, and STL is widely supported by slicers and mesh repair tools.

OBJ material files are ignored for STL output because STL does not store colors or texture references.

Inspect the resulting STL in a slicer and repair non-manifold geometry before printing.

Short answers for the practical conversion questions users ask before downloading an STL file.

Does STL keep materials and textures?

No. STL only stores triangle geometry. Materials, textures, animations, lights, and cameras are removed during conversion.

Can I 3D print the converted STL?

Yes, if the source mesh is printable. Some models may still need repair, scaling, or wall thickness adjustments before printing.

Why is my STL file larger than the original model?

STL stores raw triangle geometry and may be larger than compressed formats such as GLB or FBX.
