OBJ is a plain-text mesh format from the world of computer graphics. It stores vertices, normals, texture coordinates and polygon faces, and nearly every 3D application — Blender, Maya, 3ds Max, game engines, renderers — can read and write it, making it a dependable lowest common denominator for mesh exchange.
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.
| OBJ | USDZ | |
|---|---|---|
| Geometry | Polygon mesh | USD mesh scenes |
| Units | No | Meters (implied) |
| Colors & materials | Via MTL sidecar | PBR materials |
| Animations | No | Yes |
| Typical use | DCC tool interchange | 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 .obj 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.
The OBJ importer reads the geometry file alone; an external .mtl sidecar and its texture files are not resolved, so that material detail is absent before export. The USDZ result contains the converted geometry and flat colors, but no source textures, rigs or animation tracks.
