Convert glTF to USDZ
Convert a glTF file to USDZ in your browser. Free, no upload, no sign-up.
Convert glTF files to USDZ directly in your browser. The converter parses the glTF 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 glTF to USDZ
- 1Drop your glTF file
Drag a .gltf file onto the box above or click to choose one. Only self-contained .gltf files (embedded buffers) can be imported here, because external .bin and texture files cannot be resolved in the browser.
- 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 glTF file?
glTF is the JSON form of the same Khronos standard as GLB. The .gltf file describes the scene as readable JSON; binary buffers and textures may be embedded as base64 or kept as separate files. It is convenient when you want to inspect or edit the scene description by hand.

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.
