When to convert GLB to OBJ
Use this conversion when your destination needs OBJ and you have a GLB source. Keep the original so you can compare the result or try another supported format.
Check the output in your target application. Format conversion may change unsupported features, metadata or precision; retain the original file as your reference.

How to Convert GLB to OBJ
Follow these simple steps to convert your file in seconds.
Choose a GLB file
Select or drop one file up to 100 MB. Its extension must match this converter. Availability is checked before transfer.
Convert to OBJ
Check the output in your target application. Format conversion may change unsupported features, metadata or precision; retain the original file as your reference.
Download and check the result
Use Download after conversion completes. Open the result and check its content, quality and formatting before sharing it. Download links expire one hour after upload finishes. Uploaded and converted files are removed automatically by regular cleanup. Files may become unavailable sooner when the service restarts.
Tips for Converting GLB to OBJ
Practical advice to get the best results from this conversion.
Why this conversion is worth doing
GLB 3D Model has a known limitation: relatively newer format with less support in legacy 3D software. Wavefront OBJ 3D Model addresses this with a key advantage: widely supported by virtually all 3D modeling, rendering, and game development tools. Converting from GLB to OBJ is most worthwhile when this specific trade-off matters for the way you intend to use the file.
Match the format to the actual workflow
GLB 3D Model is most commonly used for web-based 3d content delivery with three.js, babylon.js, and webxr, while Wavefront OBJ 3D Model is the standard for 3d model interchange between different modeling and rendering software. If your workflow is closer to the second pattern, converting makes sense. If you are still working in a context where GLB is the norm, converting may create unnecessary compatibility friction with collaborators or tools that expect the source format.
Watch for this limitation in the OBJ output
Wavefront OBJ 3D Model has its own limitation worth understanding before you commit: no support for animation, rigging, or scene hierarchy. After the conversion completes, open the OBJ file and verify that this limitation does not affect your specific use case — for some workflows it is irrelevant; for others it can be a deal-breaker.
Verify geometry integrity after conversion
3D model formats represent geometry differently — some use polygon meshes, others use NURBS or subdivision surfaces. After converting from GLB to OBJ, inspect the converted model for missing faces, inverted normals, or deformed geometry. Complex models with non-manifold geometry or n-gons may not convert cleanly across all format pairs.

Source Format
GLB 3D Model
model/gltf-binaryGLB (GL Transmission Format Binary) is the binary container version of glTF 2.0, packaging the JSON scene description, binary geometry buffers, and texture images into a single self-contained file. Developed by the Khronos Group, it is designed as the "JPEG of 3D" for efficient transmission and loading of 3D content. GLB supports PBR (Physically Based Rendering) materials, skeletal animation, and morph targets.
Advantages
- Single self-contained file with geometry, textures, and materials
- Optimized for fast loading in web browsers and real-time 3D applications
- Supports PBR materials, skeletal animation, morph targets, and scene hierarchy
Limitations
- Relatively newer format with less support in legacy 3D software
- Binary format that is not human-readable for debugging or manual editing
- Texture compression within GLB varies across viewers and engines
Common Uses
- Web-based 3D content delivery with Three.js, Babylon.js, and WebXR
- AR and VR application 3D asset distribution
- Real-time 3D visualization in e-commerce and product configurators
Target Format
Wavefront OBJ 3D Model
model/objOBJ (Wavefront Object) is a widely used plain-text 3D model format that stores geometry including vertices, texture coordinates, normals, and polygon faces. Developed by Wavefront Technologies, it supports polygonal meshes with optional material and texture references through companion .mtl (Material Template Library) files. OBJ is one of the most universally supported 3D interchange formats.
Advantages
- Widely supported by virtually all 3D modeling, rendering, and game development tools
- Plain-text format that is human-readable and easy to parse or generate
- Supports texture coordinates, normals, and material references
Limitations
- No support for animation, rigging, or scene hierarchy
- Plain-text format results in large file sizes for complex models
- Material and texture information requires separate .mtl and image files
Common Uses
- 3D model interchange between different modeling and rendering software
- 3D printing with texture and material information
- Game development asset pipelines and 3D content creation
