Convert OBJ to USDZ
Convert a OBJ file to USDZ in your browser. Free, no upload, no sign-up.
Convert OBJ files to USDZ directly in your browser. The converter parses the OBJ 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 OBJ to USDZ
- 1Drop your OBJ file
Drag a .obj file onto the box above or click to choose one. The companion .mtl file and textures are ignored. Geometry is imported completely.
- 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 OBJ file?
OBJ is a plain-text mesh format from Wavefront. It stores vertices, normals, UV texture coordinates and face definitions, and references materials through a companion .mtl file. It is human-readable and supported by virtually every 3D modelling application.
Commonly used by: Blender, Maya, ZBrush, game engines, photogrammetry tools
The companion .mtl file and textures are ignored. Geometry is imported completely.
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
