2 Ways to Convert USDZ to GLB
Pick based on whether you need quick conversion or full animation control.
Online USDZ to GLB Converter (This Tool)
Best for: quick, no-install conversion
- Drag and drop your .usdz file.
- Wait for the automatic conversion.
- Download the GLB file.
Pros: Free, no software install, produces web-ready GLB.
Cons: Requires internet. Some PBR material properties may need adjustment.
Blender (Free Desktop Software)
Best for: material and animation editing
- Open Blender and import USDZ (File > Import > USDZ).
- Verify materials and animations.
- Go to File > Export > glTF 2.0 (.glb).
- Click Export.
Pros: Free. Full control over material and animation export.
Cons: Requires installing Blender.
Quick Checks Before You Convert
USDZ → GLB transfers geometry, materials, and animations. Review these items for a clean conversion.
PBR Material Conversion
USDZ uses a different material model than GLB PBR (metallic-roughness). Some material properties may not map directly. Use Blender for precise material control.
Animation Transfer
USDZ supports skeletal and morph animations. GLB also supports these. Verify that animations transfer correctly after conversion.
Scale Units
USDZ typically uses centimeters. GLB uses meters. Check the model scale in your target viewer or engine after conversion.
Texture Embedding
USDZ can embed textures or reference them externally. GLB always embeds textures in the binary. Ensure textures are accessible during conversion.
USDZ vs GLB Format Comparison
| Feature | USDZ | GLB |
|---|---|---|
| Full name | Autodesk USDZ | glTF Binary |
| Maintained by | Autodesk | Khronos Group |
| Structure | Proprietary binary | Open binary container |
| PBR materials | Limited | Yes (metallic-roughness) |
| Animations | Yes | Yes |
| Skeletal rigging | Yes | Yes |
| Web native | No | Yes (Three.js, WebGL) |
| License | Proprietary | Open (royalty-free) |
| Primary use | Game engines, desktop 3D | Web 3D, AR/VR, mobile |
| File size | Large | Compact (binary) |
Fixing Common Issues After Conversion
Typical errors after USDZ → GLB and how to resolve them.
GLB materials look different from USDZ
USDZ and GLB use different material models. Use Blender to import the USDZ, convert materials to Principled BSDF (PBR), then export as GLB.
Animations are missing or broken
Verify the USDZ contains animation data. If animations don't transfer, use Blender to import, check the Action Editor, then export GLB with animation export enabled.
Model scale is wrong in web viewer
USDZ uses centimeters; GLB uses meters. The scale should convert automatically, but verify in your target viewer. Adjust if needed.
GLB file is very large
USDZ files can be large due to embedded data. Use Blender's Draco compression in glTF export settings to reduce GLB size by 50-90%.
What Is an USDZ File?
USDZ is Apple/Pixar's AR format, a zip-based archive storing 3D geometry, materials, textures, and animations. It powers AR Quick Look on iPhone, iPad, and macOS.
USDZ vs GLB: why convert?
USDZ is Apple-only. GLB is the universal web 3D standard, loading in any browser via Three.js. Converting USDZ to GLB brings your Apple AR content to Android, Windows, and the broader web.

Frequently Asked Questions
How do I convert USDZ to GLB?
Upload your .usdz file using the converter above. The tool converts it to GLB format automatically. Download the GLB file when conversion is complete.
Is this USDZ to GLB converter free?
Yes, completely free. No registration, no watermarks, no hidden costs.
What is the difference between USDZ and GLB?
USDZ is Autodesk's proprietary format for game engines and 3D animation. GLB is the Khronos Group's open binary format for web 3D. USDZ is desktop-oriented; GLB is web-native.
Does converting USDZ to GLB preserve animations?
Both USDZ and GLB support skeletal animations and morph targets. Animation data should transfer during conversion. If animations are missing, use Blender to verify and re-export.
How do I convert USDZ to GLB in Blender?
In Blender, go to File > Import > USDZ (.usdz). Then go to File > Export > glTF 2.0 (.glb). Click Export. Materials and animations transfer automatically.
Does USDZ to GLB preserve PBR materials?
Basic material properties transfer. USDZ uses a different material model than GLB PBR (metallic-roughness). Use Blender for precise PBR conversion via Principled BSDF.
Why convert USDZ to GLB?
GLB is the standard for web-based 3D. If you need to display an USDZ model in a web browser, Three.js, or Babylon.js, convert it to GLB. GLB is open, compact, and web-native.
Can I convert USDZ to GLB on Mac?
Yes. Our online converter works in any browser on macOS. You can also use Blender on Mac.
What software opens GLB files?
GLB files can be opened by Three.js, Babylon.js, Google Model Viewer, Blender, Microsoft Paint 3D, Facebook 3D Posts, and any glTF-compatible viewer.
Is USDZ or GLB better for web 3D?
GLB is always better for web 3D. It is open, compact, and loads natively in browsers. USDZ is proprietary and requires plugins or conversion for web use.
Are my files safe?
Yes. Files are processed securely and auto-deleted after conversion. We do not store your 3D models permanently.
Can I use the converted GLB in Unity or Unreal?
Yes. Unity supports GLB via the glTFast package. Unreal Engine supports GLB via the glTF importer plugin. For native game engine support, USDZ is still preferred.
