FBX vs OBJ— what's the difference?

FBX.fbx

Autodesk's proprietary interchange format — the de-facto standard for moving rigged, animated characters between Maya, Max, Blender, Unity, and Unreal.

Strengths
  • Carries skeletal animation, blend shapes, cameras, lights
  • Supported by every major DCC and game engine
  • Binary or ASCII flavours
Limitations
  • Closed, Autodesk-controlled spec — SDK-only for authoritative reads
  • No universal web viewer — typically converted to GLB for the browser
Typical use: Character animation handoff, game engine import, DCC transfer
OBJ.obj

Human-readable Wavefront mesh format — ubiquitous in 3D graphics, game art, and asset pipelines. Pairs with a .mtl material file.

Strengths
  • Supported by virtually every 3D tool (Blender, Maya, 3ds Max, Unity, Unreal…)
  • Plain-text, easy to diff and hand-edit
  • Keeps UV coordinates and vertex normals, unlike STL
  • Material references via companion .mtl file
Limitations
  • Text format — larger on disk than binary meshes
  • No scene hierarchy, no animation, no skeletons
  • Materials live in a separate file; easy to lose
Typical use: 3D art pipelines, DCC handoff, asset archives

How to convert FBX to OBJ

  1. 1
    Drop a .fbx file on the page. Both binary and ASCII FBX variants work.
  2. 2
    Preview the geometry in 3D. The Scene Tree shows the full hierarchy from the FBX.
  3. 3
    Click Download .OBJ. Open in Blender, Maya, 3ds Max, Unity or Unreal.

FAQ

What does OBJ keep from the FBX?

Vertices, faces, UVs, vertex normals, and a flat list of named object groups. No animation, no rig, no blend shapes, no scene hierarchy beyond group names.

Is there a .mtl material file?

We emit just the geometry .obj. FBX materials don't map cleanly to OBJ's limited .mtl format, so we leave materials to your target DCC. Most workflows reassign materials on import anyway.

Is animation preserved?

No. OBJ is a static mesh format. Only the bind pose (or whatever pose the FBX is currently at) is exported.

Why is the OBJ larger than the FBX?

OBJ is plain text; FBX is binary. Expect 2–5× the size. The trade-off is universal compatibility — every 3D tool ever made reads OBJ.

Is my file uploaded?

No. Three.js' FBXLoader and OBJExporter run entirely in your browser.
