Quick Answer

To convert glTF to OBJ, drop your glTF file into the converter above. ChangeThisFile extracts the 3D mesh data from the glTF scene in your browser and exports it as an OBJ file with vertex coordinates and face definitions. The conversion is instant and your 3D model never leaves your device. Free, no signup required. Perfect for importing web 3D assets into CAD software.

glTF vs OBJ: Format Comparison

Key differences between the two formats

Feature	glTF	OBJ
Primary use	Web 3D, AR/VR, game engines	CAD, 3D modeling, rendering
Scene data	Complete 3D scenes with animations	Static geometry only
Materials	PBR materials with textures	Basic material references (.mtl)
Animation support	Skeletal and morph animations	No animation support
File structure	JSON + binary buffers	Simple text format
Web compatibility	Native browser 3D support	Requires conversion for web

When to Convert

Common scenarios where this conversion is useful

CAD software import

Import web 3D models into CAD software like Fusion 360, SolidWorks, or Blender. OBJ format provides better compatibility with traditional modeling tools.

3D printing preparation

Convert glTF models from web platforms to OBJ format for further processing into STL for 3D printing workflows.

Game asset extraction

Extract 3D models from glTF game assets and convert to OBJ for use in different game engines or offline rendering tools.

Educational projects

Convert glTF models from educational platforms to OBJ for use in classroom 3D modeling software and assignments.

Cross-platform compatibility

Convert modern glTF models to widely-supported OBJ format for sharing with users of older 3D software.

Who Uses This Conversion

Tailored guidance for different workflows

For Web Developers

Convert glTF assets from Three.js or WebGL projects to OBJ for offline rendering and analysis
Extract 3D models from web applications for use in traditional 3D modeling pipelines
Share web 3D assets with designers using desktop CAD software

Check that UV coordinates transfer correctly for texture mapping in your target software

Consider mesh complexity when converting from optimized web models to CAD workflows

For 3D Artists

Import glTF models from web platforms into Blender, Maya, or 3ds Max for further modeling
Convert AR/VR glTF assets to OBJ for traditional rendering pipeline integration
Extract geometry from glTF scenes for use in offline visualization projects

Be aware that PBR materials will need to be recreated in your target software

Check mesh normals after import to ensure proper shading in your renderer

For Game Developers

Convert glTF assets between different game engines that prefer OBJ format
Extract static meshes from glTF scenes for use in engines without glTF support
Prepare web 3D models for import into Unity or Unreal Engine via OBJ workflow

Note that animations and skeletal data will be lost in the conversion

Consider polygon count and optimization for your target game engine

Frequently Asked Questions

Will animations and materials be preserved in the OBJ conversion?

No, OBJ format only stores static geometry. glTF animations, PBR materials, and scene hierarchies are not included in the converted OBJ file.

Can I convert glTF files with multiple meshes?

Yes, all meshes in the glTF scene are combined into a single OBJ file. For separate objects, you'll need to export each mesh individually from your 3D software.

Does the conversion handle glTF binary (.glb) files?

The converter is optimized for text-based glTF (.gltf) files. For .glb files, first convert to .gltf format using other tools, then use this converter.

Are texture coordinates preserved during conversion?

Yes, UV coordinates from the glTF are transferred to the OBJ file, allowing you to apply textures in your target 3D software.

Will the OBJ work in my CAD software?

OBJ is widely supported. Most CAD programs (Fusion 360, SolidWorks, Blender, Maya) can import OBJ files for further modeling and analysis.

Does the conversion preserve the original scale?

Yes, the conversion maintains exact scale and proportions from the glTF file. No automatic scaling or unit conversion is applied.

Can I convert glTF models from web browsers?

Yes, this works with glTF files from any source: Three.js exports, WebGL applications, AR/VR platforms, or game engines.

What happens to PBR materials in the glTF?

Material information is lost since OBJ has limited material support. You can create .mtl material files manually in your 3D software after import.

Is the glTF to OBJ conversion reversible?

You can convert OBJ back to other formats, but glTF-specific features like animations, PBR materials, and scene structure cannot be recovered.

Are there size limitations for glTF conversion?

The conversion runs in your browser, so very large glTF files (>100MB) may process slowly. Most web 3D models convert quickly without issues.
