Free 3D converter

Convert FBX to OBJ

Drop a FBX file and download it as OBJ. The conversion runs in your browser, so the file never leaves your device. It keeps the exact shape and the colour texture.

Free, no sign-up, and your file stays on your device.

Converted to OBJ in your browser. Nothing is uploaded.

GLB, glTF, OBJ, STL, PLY, FBX or 3MF, up to 300 MB. Add .mtl, .bin and texture files alongside.

What carries over from FBX to OBJ

Checked against what the converter writes, not just what the formats allow.
Shape (triangles)
Kept exactly
UV coordinates

Colour texture
Kept, in a .zip with the .mtl
PBR maps (roughness, metalness, normal)
Dropped: OBJ can't store it
Vertex colours
Dropped: OBJ can't store it
Animation
Dropped: OBJ can't store it
Separate parts

Size and units
Written in centimetres; OBJ doesn't record units.

Unchanged.

How to convert FBX to OBJ

  1. Add your FBX

    Drop the FBX file, with its textures if it has separate ones.

  2. Check the preview

    Turn the model and check what will be kept before converting.

  3. Download the OBJ

    The .obj (or a .zip with textures) is written in a second or two for most models.

When to convert FBX to OBJ

  • For an app that doesn't read your format

    OBJ is the lowest common denominator: almost every 3D app (Blender, Maya, 3ds Max, Cinema 4D, ZBrush), Unity and Roblox Studio natively, and every major slicer.

  • To edit the mesh

    Plain-text geometry with UVs is easy to inspect, clean up and re-import.

The two formats

FBX

Autodesk FBX

FBX is Autodesk's proprietary interchange format, originally Kaydara's FiLMBOX from the 1990s. It carries meshes, materials, skeletons and animation, which made it the default for game engines and Mixamo.

Usually comes from
Mixamo, Maya, 3ds Max, game asset stores and Unity or Unreal projects
Opens in
Unity, Unreal Engine, Godot, Roblox Studio, Blender, Maya, 3ds Max and Mixamo
Units
Centimetres times a scale factor stored in the file
Up axis
Set in the file

OBJ

Wavefront OBJ

OBJ is the plain-text mesh format Wavefront Technologies introduced in the late 1980s. It stores vertices, UVs, normals and faces; materials and texture maps live in a companion .mtl file.

Usually comes from
older asset libraries, CAD and DCC exports, and photogrammetry apps
Opens in
almost every 3D app (Blender, Maya, 3ds Max, Cinema 4D, ZBrush), Unity and Roblox Studio natively, and every major slicer
Units
None recorded
Up axis
Not recorded (usually Y up)

Questions

Something else? Ask us and a person will answer.

Is this FBX to OBJ converter free?

Yes. There is no account, watermark or limit on conversions. It accepts files up to 300 MB; how large a model your browser can handle depends on your device's memory.

Is my file uploaded?

No. The conversion runs in your browser with the open-source three.js loaders and exporters, so your FBX never leaves your device.

Are textures included in the OBJ?

If the model has a colour texture, you get a .zip with the .obj, its .mtl and the texture as PNG. Keep them in one folder when you import. OBJ has no standard for PBR maps, so roughness, metalness and normal maps are left out.

Are FBX textures included?

Textures embedded in the FBX are. If yours sit next to the FBX as separate files, select them together with it.

Can I make a 3D model from a photo instead?

Yes. PhotoGenius turns a photo or a text prompt into a textured GLB with Rodin Gen-2.5, Rodin Gen-2.5 Fast, Tripo H3.1, TRELLIS.2, Rodin Gen-2 or Hunyuan3D 3.1, which you can then convert here. See Image to 3D model.

Turn a photo into a 3D model

Rodin Gen-2.5, Rodin Gen-2.5 Fast, Tripo H3.1, TRELLIS.2, Rodin Gen-2 or Hunyuan3D 3.1 builds a textured GLB from one image. The price shows before you run it.
