How can I convert my OBJ file to GLTF?

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

How long does it take to convert my OBJ to GLTF?

Most OBJ to GLTF 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 OBJ to GLTF conversion preserve?

Materials, UV maps, vertex normals, and scene hierarchy are preserved wherever the GLTF 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 OBJ to GLTF work?

In order to successfully convert a OBJ formatted file to the GLTF format, our converter tools will perform several initial checks to ensure the file provided is indeed a OBJ 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 OBJ file to convert yet?

Browse the FurniMesh 3D furniture library — every model exports natively to GLTF (visit https://furnimesh.com/library/format/gltf/ for the GLTF catalog). Or generate a custom 3D model from any furniture photo with the Image to 3D AI generator at https://furnimesh.com/image-to-3d/ — output formats include GLTF natively.

File Formats

File format information for OBJ and GLTF

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

OBJ Format

Extension:OBJ

Full Name:Wavefront OBJ

Type:3D Model

Mime Type:model/obj

Format:Binary

Opens With:Blender, Maya, 3ds Max

OBJ (Wavefront Object): A widely-used, open file format (.obj) for 3D geometry, storing vertex, texture, and normal data. Developed by Wavefront Technologies, it's simple and supports interoperability across 3D software.

OBJ Converter Capabilities

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

GLTF Format

Extension:GLTF

Full Name:GL Transmission Format

Type:3D Model

Mime Type:model/gltf+json

Format:Binary

Opens With:Blender, MeshLab

glTF (GL Transmission Format): An open, JSON-based file format (.gltf) for efficient 3D model delivery. It supports geometry, materials, and animations, designed for web and cross-platform compatibility.

About the OBJ to GLTF converter

FurniMesh's OBJ to GLTF 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 GLTF 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).
