OFF is a minimal academic mesh format: a vertex list and a face list in plain text, nothing else. Its simplicity makes it a favorite in computational-geometry research, mesh-processing courses and tools like CGAL and MeshLab.
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.
| OFF | USDZ | |
|---|---|---|
| Geometry | Polygon mesh | USD mesh scenes |
| Units | No | Meters (implied) |
| Colors & materials | Optional vertex colors | PBR materials |
| Animations | No | Yes |
| Typical use | Research & geometry processing | 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 .off 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.
OFF vertex colors are not carried through the converter’s flat per-part color model, and the format supplies no reliable units. The USDZ result contains the converted geometry and flat colors, but no source textures, rigs or animation tracks.
