2 Ways to Convert FBX to USDZ
Pick based on whether you need quick conversion or full animation control.
Online FBX to USDZ Converter (This Tool)

- Drag and drop your .fbx file.
- Wait for the automatic conversion.
- Download the USDZ file.
Pros: Free, no software install, produces web-ready USDZ.
Cons: Requires internet. Some PBR material properties may need adjustment.
Blender (Free Desktop Software)
Best for: material and animation editing
- Open Blender and import FBX (File > Import > FBX).
- 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
FBX → USDZ transfers geometry, materials, and animations. Review these items for a clean conversion.
PBR Material Conversion
FBX uses a different material model than USDZ PBR (metallic-roughness). Some material properties may not map directly. Use Blender for precise material control.
Animation Transfer
FBX supports skeletal and morph animations. USDZ also supports these. Verify that animations transfer correctly after conversion.
Scale Units
FBX typically uses centimeters. USDZ uses meters. Check the model scale in your target viewer or engine after conversion.
Texture Embedding
FBX can embed textures or reference them externally. USDZ always embeds textures in the binary. Ensure textures are accessible during conversion.
FBX vs USDZ Format Comparison
| Feature | FBX | USDZ |
|---|---|---|
| Full name | Autodesk FBX | 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 FBX → USDZ and how to resolve them.
USDZ materials look different from FBX
FBX and USDZ use different material models. Use Blender to import the FBX, convert materials to Principled BSDF (PBR), then export as USDZ.
Animations are missing or broken
Verify the FBX contains animation data. If animations don't transfer, use Blender to import, check the Action Editor, then export USDZ with animation export enabled.
Model scale is wrong in web viewer
FBX uses centimeters; USDZ uses meters. The scale should convert automatically, but verify in your target viewer. Adjust if needed.
USDZ file is very large
FBX files can be large due to embedded data. Use Blender's Draco compression in glTF export settings to reduce USDZ size by 50-90%.
What Is an FBX File?
FBX (Filmbox) is a proprietary 3D file format developed by Autodesk. It stores geometry, materials, textures, animations, skeletal rigging, morph targets, cameras, lights, and scene hierarchy.
FBX is the industry standard for game development and 3D animation, natively supported by Unity, Unreal Engine, Maya, 3ds Max, and Blender.
FBX vs USDZ: why convert?
FBX is proprietary and desktop-oriented. USDZ is open, web-native, and loads in any browser via Three.js. Converting FBX to USDZ enables your models to appear in AR Quick Look on iPhone and iPad.

Frequently Asked Questions
How do I convert FBX to USDZ?
Upload your .fbx file using the converter above. The tool converts it to USDZ format automatically. Download the USDZ file when conversion is complete.
Is this FBX to USDZ converter free?
Yes, completely free. No registration, no watermarks, no hidden costs.
What is the difference between FBX and USDZ?
FBX is Autodesk's proprietary format for game engines and 3D animation. USDZ is the Khronos Group's open binary format for web 3D. FBX is desktop-oriented; USDZ is web-native.
Does converting FBX to USDZ preserve animations?
Both FBX and USDZ 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 FBX to USDZ in Blender?
In Blender, go to File > Import > FBX (.fbx). Then go to File > Export > glTF 2.0 (.glb). Click Export. Materials and animations transfer automatically.
Does FBX to USDZ preserve PBR materials?
Basic material properties transfer. FBX uses a different material model than USDZ PBR (metallic-roughness). Use Blender for precise PBR conversion via Principled BSDF.
Why convert FBX to USDZ?
USDZ is the standard for web-based 3D. If you need to display an FBX model in a web browser, Three.js, or Babylon.js, convert it to USDZ. USDZ is open, compact, and web-native.
Can I convert FBX to USDZ on Mac?
Yes. Our online converter works in any browser on macOS. You can also use Blender on Mac.
What software opens USDZ files?
USDZ 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 FBX or USDZ better for web 3D?
USDZ is always better for web 3D. It is open, compact, and loads natively in browsers. FBX 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 USDZ in Unity or Unreal?
Yes. Unity supports USDZ via the glTFast package. Unreal Engine supports USDZ via the glTF importer plugin. For native game engine support, FBX is still preferred.
