OBJ to STL OBJ to STL

Convert a Wavefront OBJ model into an STL surface mesh for CAD software, slicing or 3D printing. STL does not preserve materials, texture references, object groups or reliable units from the uploaded model. Check the scale, normals, holes and non-manifold geometry in your CAD program or slicer.

Conversion settings

Choose settings before adding files. The same settings apply to the whole batch.

More options

A scale of 1 preserves the original size. Scaling changes the geometry, not the declared measurement units.

Quick start

Convert a Wavefront OBJ model into an STL surface mesh for CAD software, slicing or 3D printing.

  1. Upload the OBJ model
  2. Start the STL conversion
  3. Download and inspect mesh scale and integrity

OBJ to STL

Upload an OBJ 3D model and save it as STL. Conversion runs on the server through Assimp and is useful for preparing models for preview, 3D printing, editor exchange or web publishing.



OBJ is a 3D model file format. Inettools converters use it for uploading, previewing and converting 3D models between supported formats.
