Please note: Your OBJ file, once uploaded to our server will be deleted 15 minutes after upload so please download your converted OBJ file before this time.
Here are 2 simple steps to convert your OBJ to STL using our fast and free OBJ converter tool.
| Extension | OBJ |
| Full Name | Wavefront |
| Type | 3D Model |
| Mime Type | text/plain |
| Format | Text |

The OBJ file format originally created by Wavefront Technologies and later adopted by many other 3D software vendors is a simple text-based file format for describing 3D model/geometry. This data can include Vertices, Faces, Normals, Texture Coordinates and references to external Texture files.
As the format is text-based it is relatively straight-forward to parse by 3D modelling applications. A downside of the text-based format is the files can be rather large compared to similar binary formats such as STL and compressed files such as 3MF.
OBJ Converter Capabilities
Our OBJ 3D Model/Mesh tool does not support any color material data contained within OBJ files so the converted file will not contain any color information.
| Extension | STL |
| Full Name | Standard Triangle Language |
| Type | 3D Model |
| Mime Type | application/vnd.ms-pki.stl |
| Format | Text |
| Opens With | Blender, MeshLab, CAD Assistant, DAZ Studio |
The STL file format has its roots in the 1980's and is the native file format for 3D Systems stereolithography CAD software. The format defines a triangulated mesh with vertices and faces and is a popular format for sharing 3D printable model files.
There were several formats that attempted to extend the STL format namely SolidView and VisCAM whose formats included limited 15-bit color information for each mesh face which is often ignored by most modern 3D software. The STL format can be either Text or Binary, our tools will support both formats.
STL Converter Capabilities
Our 3D conversion tool does not support color/material information in STL files so your file will not contain any color information.
Your OBJ file will be converted to a STL file using our unified 3D model and mesh conversion tool. Our OBJ 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals and relevant material information. Our tool will not attempt to transfer any color information if present in your OBJ file, your final 3D model will contain geometry data only.
First click the "Upload..." button, select your OBJ file to upload. Your OBJ file will be uploaded to our servers. When the OBJ to STL conversion has completed, you can download your STL file straight away.
We aim to process all OBJ to STL conversions as quickly as possible, this usually takes around 5 seconds however this can be longer for certain files, so please be patient.
We aim to provide the best conversion experience. Our tools are under constant review and development with new features being added every week.
