FBX and USDZ, explained
What is FBX?
FBX is Autodesk's proprietary scene format and the long-standing standard for moving rigged, animated characters between DCC tools and game engines. Skeletons, skinning, blend shapes, and animation clips all travel inside one file.
Because the format is closed, no official browser tooling exists - this fleet writes FBX through assimp's open-source FBX writer running as WebAssembly, right in your browser. Static geometry with UVs is the reliable path; rigs and animation clips need a DCC-tool export.

What is USDZ?
USDZ is Apple's AR format: Pixar's Universal Scene Description packed into a single file that iPhones and iPads open natively in AR Quick Look - no app required. E-commerce product previews on Apple devices run on USDZ.
USDZ shines on Apple platforms and almost nowhere else, so the common workflows are converting a GLB into USDZ to ship an AR preview, or unpacking a USDZ back into GLB/OBJ to edit it in standard tools.

What survives the fbx to usdz conversion
Format conversion is honest work: some data has nowhere to go in the target format. Here is exactly what carries over.
Mesh geometry
All meshes carry over exactly, with scene transforms baked in; rigged characters export in rest pose.
Embedded textures
Textures embedded in the FBX carry into the USDZ; externally-referenced texture files are not part of the single file you drop.
Scale interpretation
FBX commonly uses centimeters; USD assumes meters. Numbers copy 1:1, so a cm-authored asset appears 100x large in AR - scale by 0.01 first.
Rig & animations
The conversion targets static AR previews - clips and skeletons are not carried.
When should you convert FBX to USDZ?
Convert to USDZ to demo game assets in the real world: a character standing on the client's table, a prop at true scale - straight from an iPhone, no engine build required.
Keep the FBX for production - engines and DCC tools want it, and it holds the rig and animation the USDZ preview drops.
And if what you actually need is a new model rather than a new file format: 3D AI Studio's main tool can generate 3D models from photos with AI - with exports to every format on this page.
