What 3D File Formats Do You Support?

Learn which 3D file formats Meshy supports for upload and export — .fbx, .obj, .glb, .stl, .gltf, .usdz and more.

Supported upload file formats

Meshy supports uploading 3D models in the following formats:

  • .fbx – Filmbox, widely used for rigged characters and animation pipelines

  • .obj – Wavefront OBJ, a portable and broadly compatible mesh format

  • .stl – Stereolithography, commonly used in 3D printing workflows

  • .gltf – GL Transmission Format (text-based, with external assets)

  • .glb – GL Transmission Format (binary, single self-contained file)

Maximum file size: 100 MB per upload.

How to upload

To upload a 3D model in Meshy:

  1. Go to Workspace and click "Upload Model" on the top-right corner and select your file from your device.

  2. Wait for the upload to complete before starting the texturing process.

Upload requirements

  • Upload one model at a time — batch uploads are not supported.

  • File must be within the 100 MB size limit.

  • Structure & Content

    • Remove any non-mesh elements, such as cameras and lights, from the model file.

    • Remove any animations and shape keys from the model file.

    • We recommend to only include one mesh in the model file. If the file contains multiple meshes, they will be merged after uploading.

  • Alignment & Positioning

    • Make sure that the model is facing the correct front axis in your modeling software.

    • For best results, the model needs to be centered at world origin.

  • Texture & UV Requirements

    • When Keep Original Texture and UV is turned on, please make sure that the model only contains 1 material and 1 UV map after merging the objects.

    • UV islands cannot overlap or be shared among multiple parts of the model.

Export file formats

Once your model is generated or textured, you can download it in the following formats:

  • .fbx – Filmbox, ideal for game engines (Unity, Unreal) and animation pipelines

  • .obj – Wavefront OBJ, widely compatible across most 3D software

  • .usdz – Universal Scene Description (zip), optimized for AR on iOS

  • .glb – GL Transmission Format (binary), best for web and real-time applications

  • .stl – Stereolithography, standard for 3D printing

  • .blend – Blender native format, for continued editing in Blender

  • .3mf / .dmf – 3D Manufacturing Format, used in printing and fabrication workflows

FAQ

1.My upload failed — what should I check?

Verify that your file uses a supported format (.fbx, .obj, .stl, .gltf, or .glb) and is under 100 MB. If the file passes both checks, try re-exporting it from your 3D software to rule out corruption. If the problem persists, please reach out to our support team via the chat widget.

2.Which export format should I use?

It depends on where you plan to use the model:

  • Use .glb for web, WebXR, or real-time rendering.

  • Use .fbx for game engines like Unity or Unreal Engine.

  • Use .usdz for iOS AR experiences (Reality Composer, Quick Look).

  • Use .stl or .3mf for 3D printing.

  • Use .blend to continue editing in Blender.
