GLB and USDZ, explained
What is GLB?
GLB is the binary form of glTF, often called "the JPEG of 3D". One file packs the full scene: meshes, PBR materials, embedded textures, animations, and a real unit scale (meters). It is the standard for 3D on the web and the default output of most AI 3D generators.
Because everything is embedded in a single binary file, GLB transfers cleanly between tools with nothing lost in transit. glTF/GLB is an open Khronos standard, loads fast, and is supported by every modern engine, DCC tool, and web viewer.
- Developed by
- Khronos Group (2015)
- Structure
- Single binary file: JSON scene + buffers + textures
- Used by
- Web viewers, Three.js, Unity, Unreal, AR apps, e-commerce platforms
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 glb 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
Every mesh carries over exactly, with scene transforms baked in.
PBR materials & textures
GLB's embedded textures and material properties translate to USD's preview surface - the model looks the same in AR.
Real-world scale
Both formats use meters, so a correctly-scaled GLB appears at true size in AR Quick Look.
Animations
This conversion targets static AR previews; animation clips are not carried.
Vertex colors
USD preview materials favor textures; vertex-color-only models may appear plain in Quick Look.
When should you convert GLB to USDZ?
Convert to USDZ to reach Apple AR: iPhones and iPads open USDZ natively in AR Quick Look from Safari, Messages, or Mail - no app needed. E-commerce 'view in your room' experiences on Apple devices run on exactly this.
Keep the GLB for everything else - Android's Scene Viewer, web viewers, and engines all want glTF. Ship both: GLB for the web and Android, USDZ for Apple.
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.
