glTF is the Khronos royalty-free standard for transmitting 3D scenes. The JSON variant keeps the scene description human-readable with geometry in sidecar buffers, and the ecosystem — Babylon.js, Unity, Unreal, Blender and the browser engines — treats it as the native interchange format for real-time 3D.
USDZ packages Pixar’s Universal Scene Description into a single uncompressed ZIP for Apple’s AR Quick Look. An iPhone or iPad can open a USDZ link directly into augmented reality from Safari — no app required — which makes it the format for AR product previews on Apple devices.
| glTF | USDZ | |
|---|---|---|
| Geometry | GPU-ready triangle mesh | USD mesh scenes |
| Units | Meters by spec | Meters (implied) |
| Colors & materials | Full PBR materials | PBR materials |
| Animations | Yes | Yes |
| Typical use | Real-time engines & web pipelines | Apple AR Quick Look |
Yes — free with no accounts, no watermarks and no file-size limits. Conversion runs on your own machine, so there are no server costs behind it.
No. The converter runs entirely in your browser using WebAssembly. Your .gltf file never leaves your device, which makes it safe for confidential designs.
Yes — parts and assembly hierarchy are preserved where USDZ supports them, and you can optionally merge everything into a single mesh during conversion.
Yes. Every converted model opens in the built-in 3D viewer with an assembly tree, display modes and section views, so you can inspect the result first.
glTF can contain textures and animation, but this converter carries geometry, hierarchy and one flat base color per part; texture maps, rigs and animation tracks are omitted. The USDZ result contains the converted geometry and flat colors, but no source textures, rigs or animation tracks.
