How can I convert my 3DS file to OFF?

First, click the "Upload..." button and select your 3DS file to upload. Your 3DS file will be uploaded to our servers. When the 3DS to OFF conversion has completed, you can download your OFF file right away.

How long does it take to convert my 3DS to OFF?

Most 3DS to OFF conversions complete in a few seconds for typical furniture-model files (a few MB to ~100 MB). The pipeline runs in your browser for most format pairs — no upload to a server, no roundtrip latency. For SKP and BLEND outputs the conversion runs server-side via the native Blender or SketchUp engine, with a hard 5-minute timeout per conversion; most server-side conversions finish in well under a minute.

What does the 3DS to OFF conversion preserve?

Materials, UV maps, vertex normals, and scene hierarchy are preserved wherever the OFF format supports them. STL is the exception — it is a geometry-only format by design and discards materials and UVs. GLB and GLTF preserve embedded textures inside the file; OBJ produces an accompanying MTL material descriptor; SKP groups components logically with materials applied; BLEND preserves the full Blender scene graph with modifiers.

How does converting 3DS to OFF work?

In order to successfully convert a 3DS formatted file to the OFF format, our converter tools will perform several initial checks to ensure the file provided is indeed a 3DS file. There are many files out there where the file type extension does not match the data contained within the file. Along with these file type checks, our tools will do additional checks to ensure the file is correctly formatted to match the provided file type.

What if I don't have a 3DS file to convert yet?

Browse the FurniMesh 3D furniture library at https://furnimesh.com/library/ — every model exports as GLB, OBJ, SKP, or BLEND, and this converter can transform any of those to OFF. Or generate a custom 3D model from any furniture photo with the Image to 3D AI generator at https://furnimesh.com/image-to-3d/.

File Formats

File format information for 3DS and OFF

Detailed information about the source and target file formats, including their capabilities and specifications.

3DS Format

Extension:3DS

Full Name:3D Studio

Type:3D Model

Mime Type:application/octet-stream

Format:Binary

Opens With:3ds Max, Blender

3DS (3D Studio): A proprietary file format (.3ds) developed by Autodesk for 3D Studio. It stores 3D models, materials, and animations but has size limitations and is less common today.

3DS Converter Capabilities

When converting 3D model or mesh files using our 3DS converter, we will attempt to convert color materials into a suitable format for use in the converted file.

OFF Format

Extension:OFF

Full Name:Object File Format

Type:3D Model

Mime Type:application/octet-stream

Format:Binary

Opens With:MeshLab, Research Tools

OFF (Object File Format): A simple, open file format (.off) for 3D geometry, storing polygonal meshes with vertices and faces. It’s lightweight, mainly used in research and academic applications.

OFF Converter Capabilities

When converting 3D model or mesh files using our OFF converter, we will attempt to convert color materials into a suitable format for use in the converted file.

About the 3DS to OFF converter

FurniMesh's 3DS to OFF converter runs entirely in your browser using a WebAssembly glTF/3D-mesh pipeline — your file never leaves your tab, and the conversion completes in seconds for typical furniture-model files. Materials, UV maps, and scene hierarchy are preserved wherever the OFF format supports them. There's no sign-up, no watermark, no per-file size cap enforced by the UI — practical limits depend on your browser's available memory.

FurniMesh natively outputs four formats — GLB, OBJ, SKP (SketchUp 2017+), and BLEND (Blender 3.0+). Bridge conversion via this converter additionally produces FBX, STL, GLTF, 3DM (Rhino), IFC, DAE, PLY, OFF, 3DS, and 3MF. Use the converter to bridge between any combination — or skip the conversion step entirely if you don't have a source file yet (the FurniMesh library ships every model in all four native formats pre-rendered).
