how to convert fbx to obj
Drop your FBX file
Drag your FBX file into the drop zone above, or click the box to pick a file from your computer or phone. The browser reads the file directly — nothing uploads.
Click Convert
The page runs three.js on your device to decode the Filmbox and encode it as Wavefront OBJ. Most conversions finish in a few seconds; large or codec-heavy files (RAW, video) can take longer.
Download the OBJ file
When the conversion finishes, the OBJ file is ready to download. Save it anywhere on your device.
FAQ
common questions
Will I lose my FBX's animations?
Yes — OBJ is a static mesh format with no animation support. Any rigs, skeletal animations, blend shapes, or keyframe animations in the FBX are stripped during conversion; the OBJ captures only the geometry at the FBX's bind pose or current frame. For preserving animation, glTF / GLB is the better target format.
What about materials and textures?
Materials transfer to an MTL sidecar file (OBJ's standard for material definitions). Textures transfer as references — the OBJ / MTL files reference texture files that need to be kept alongside. PBR (physically-based rendering) materials in FBX may simplify because OBJ's material model is older and less expressive than FBX's.
Why convert FBX to OBJ when glTF preserves more?
Compatibility with older tools. Some 3D applications, game engines, and 3D-printing workflows have weak FBX support but rock-solid OBJ support. If your downstream tool is older or specifically expects OBJ, conversion makes sense. For modern engines and web use, glTF / GLB is the better choice.
Will the geometry be identical?
Yes — every mesh in the FBX becomes geometry in the OBJ. Vertices, faces, normals, and UV coordinates transfer cleanly. Multiple meshes in the FBX are typically concatenated or organised as groups in the OBJ (using OBJ's `g` group tag). The visual mesh is preserved exactly.
Will the OBJ files be smaller or larger than the FBX?
Usually larger. FBX is a compact binary format with efficient mesh encoding; OBJ is text-based and verbose. A 20 MB FBX commonly produces 30–50 MB of OBJ + MTL + texture files. The size jump is the cost of OBJ's broader compatibility and text-based inspectability.
