Convert GLB to USDZ
Convert a GLB file to USDZ in your browser. Free, no upload, no sign-up.
Convert GLB files to USDZ directly in your browser. The converter parses the GLB mesh, rebuilds it in memory and writes it out as USDZ, keeping every triangle. Nothing is uploaded, there is no file size limit beyond your computer's memory, and the result downloads instantly. USDZ lets iPhone and iPad users view the model in augmented reality directly from Safari, with no app required.
How to convert GLB to USDZ
- 1Drop your GLB file
Drag a .glb file onto the box above or click to choose one.
- 2Check the preview
The model renders in 3D so you can confirm it loaded correctly. Dimensions, volume and triangle count are shown next to it; open edges are flagged if the mesh is not watertight.
- 3Download the USDZ
Adjust the export options if needed and click download. Geometry and basic materials are exported. Meshes without materials get a neutral gray so AR Quick Look renders them.
What is a GLB file?
GLB is the binary container for glTF 2.0, the "JPEG of 3D" maintained by the Khronos Group. A single .glb file bundles geometry, PBR materials, textures and animations, and is the standard format for 3D on the web and in AR viewers.
Commonly used by: web viewers (three.js, model-viewer), AR on iOS and Android, Sketchfab, game engines
What is a USDZ file?
USDZ is Apple's packaging of Pixar's Universal Scene Description. It is the format iOS uses for AR Quick Look: open a .usdz link in Safari and the model appears in your room through the camera. It stores meshes, PBR materials and textures in a single uncompressed ZIP.
Commonly used by: Apple AR Quick Look, iPhone and iPad, Reality Composer, Pixar USD pipelines
USDZ lets iPhone and iPad users view the model in augmented reality directly from Safari, with no app required.
