Convert STL 3D model files into clean OBJ mesh files online. Upload your STL model, convert triangles into OBJ faces, preview model details, and download the result instantly.
Useful for 3D printing workflows, game assets, modeling software, CAD exports, mesh editing, and model sharing.
Upload an ASCII or binary STL file and convert it into a downloadable OBJ mesh file.
Upload an STL file and click convert to generate an OBJ model.
An STL to OBJ Converter helps change 3D printing mesh files into a format that many 3D modeling and editing tools can open.
Select an ASCII or binary STL file and convert its triangle mesh into OBJ format.
The converter writes OBJ vertices and faces so the mesh can be opened in many 3D tools.
Get a downloadable .obj file for modeling, editing, rendering, or asset workflows.
STL to OBJ conversion changes a stereolithography mesh file into a Wavefront OBJ model file. STL is commonly used for 3D printing, while OBJ is widely used in modeling, rendering, and game asset workflows.
This tool reads the STL triangles, exports each triangle vertex as an OBJ vertex, creates OBJ face lines, and gives you a downloadable model file.
| Feature | Purpose | Use Case |
|---|---|---|
| STL Upload | Load 3D triangle mesh | 3D printing files |
| Binary STL Support | Read compact STL files | Large mesh models |
| ASCII STL Support | Read text-based STL files | Editable mesh exports |
| OBJ Output | Create standard model file | 3D modeling tools |
| Model Details | Show vertices, faces, and bounds | Quick verification |
Convert STL to OBJ in three simple steps.
Choose an ASCII or binary .stl model file from your device. The maximum file size is 100 MB.
The tool reads STL triangles, writes OBJ vertex lines, and creates face definitions.
Download the converted .obj file and open it in your 3D modeling or rendering software.
