FBX is Autodesk’s proprietary scene format and the long-time workhorse of game development and animation pipelines. It carries meshes, rigs, skinning, animation takes and materials between tools like Maya, 3ds Max, Blender, Unity and Unreal.
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.
| FBX | OFF | |
|---|---|---|
| Geometry | Polygon mesh scenes | Polygon mesh |
| Units | Yes | No |
| Colors & materials | Materials & textures | Optional vertex colors |
| Animations | Yes — rigs & takes | No |
| Typical use | Game & animation pipelines | Research & geometry processing |
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 .fbx file never leaves your device, which makes it safe for confidential designs.
Yes — parts and assembly hierarchy are preserved where OFF 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.
FBX can contain textures and animation, but this converter carries geometry, hierarchy and one flat base color per part; texture maps, rigs and animation tracks are omitted. The OFF result is unitless geometry with no assembly hierarchy, materials, textures or animation.
