GLB is the single-file binary packaging of glTF, the "JPEG of 3D". One file carries geometry, materials, textures and animations, optimized for fast GPU loading. It is the standard for web 3D, AR on Android, e-commerce product viewers and real-time applications.
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.
| GLB | 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 | Web, AR & real-time delivery | 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 .glb 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.
GLB 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.
GLB is the binary form of glTF — the standard format for 3D on the web and in AR. What GLB files contain, how to open them free, and how to convert to and from GLB.
