Free 3D converter

Convert FBX to USDZ

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

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

How to convert FBX to USDZ

  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 USDZ

    The .usdz is written in a second or two for most models.

When to convert FBX to USDZ

  • To show it in AR on an iPhone

    Send the USDZ in Messages or Mail, or link it from a web page, and it opens in AR Quick Look at real size.

  • For product pages

    Apple devices place a USDZ in the room; pair it with a GLB for Android and the web.

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

USDZ

Universal Scene Description, zipped

USDZ packs a Pixar USD scene and its textures into one uncompressed zip. Apple and Pixar introduced it in 2018 as the format for AR Quick Look.

Usually comes from
Reality Composer, Apple's Object Capture and USD pipelines
Opens in
AR Quick Look on iPhone, iPad and Vision Pro, Quick Look on Mac, and USD tools such as Blender

Questions

Something else? Ask us and a person will answer.

Is this FBX to USDZ 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.

Does the USDZ keep materials and textures?

Yes. Colour, roughness, metalness, normal and emissive maps are written as USD preview materials, which AR Quick Look shows. Animation and vertex colours aren't written.

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.
