Free Online LWO to STL Converter

You can use our LWO to STL conversion tool to quickly convert your 3D model (with optional texture files) for free. You may upload up to 20 files at one time, and our batch LWO to STL converter will process each 3D model and present you with a download link for each file once completed.

Select File(s)

Or drag and drop your files here to upload.
A maximum of 20 files can be uploaded at once.

Please note: Your LWO file, once uploaded to our server, will be deleted 15 minutes after upload, so please download your converted LWO file before this time.

Our 3D model LWO to STL tool will load your LWO file and, where supported, attempt to extract all the relevant 3D features, such as geometry, textures, and animations. To access the 3D conversion configuration options, click the button when you have selected your files. The current options support the ability to voxelize your 3D model and more.

File format information for LWO and STL

Extension	LWO
Full Name	LightWave Object File
Type	3D Model
Mime Type	application/octet-stream
Format	Binary

Created for the LightWave 3D modeling software, the LWO file format is designed to store complex 3D scenes in a fast and easy-to-process manner. The content stored includes 3D models, their associated materials and textures, and other data to represent the final 3D scene.

The 3D data is stored within the LWO file in binary form. The data consists of the 3D objects that make up the LightWave scene, including camera properties, 3D object geometry, including their vertices, faces, and texture coordinates where appropriate. The binary format ensures LWO files remain compact and size-efficient.

Support for importing LWO files can be found in some 3D editing applications; however, for best results, it is recommended to edit LWO files directly within the LightWave 3D software.

LWO Converter Capabilities

Our LWO 3D Model/Mesh tool does not support any color material data contained within LWO 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, or Standard Triangle Language, file format has been around since the '80s and is supported by most modern 3D modeling applications. In particular, the STL format has become something of a standard format within the area of 3D printing, despite the rise of more modern formats such as 3MF.

STL files come in two flavors: binary or text format. The text format is human-readable, making it easy to perform manual edits, but can lead to very large file sizes. As you can imagine, the binary format is much more compact and represents the majority of the STL files you are likely to encounter.

The format itself is very simple; the 3D model is represented by a sequential list of triangles, with each triangle defined with 3 points consisting of their X, Y, and Z positions, along with an additional vector that contains the face normal (the direction the face is pointing). There is an additional attribute block for each triangle; however, this is largely unused and thus unsupported.

STL Converter Capabilities

Our 3D conversion tool does not support color or material information in STL files, so your file will not contain any color information.

Information for converting from LWO to STL

Your LWO file will be converted to a STL file using our unified 3D model and mesh conversion tool. Our LWO 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 it is present in your LWO file; your final 3D model will contain only geometry data.
