Spatial Favicons

Traditionally favicons are flat, 2D images. When transitioning to the immersive-web, your favicons can also be 3D images.

Supported 3D Models

• glTF Binary (.glb)

Enabling 3D favicon on websites

To enable a 3D favicon for a website, use the <link> element as you would with a 2D favicon, but change the mime type to match the icon.

/* Sample using glTF binary */
<link rel=icon href=3dicon.glb type="model/gltf-binary">

Guidance

• See the 3D Favicons Guide for specific asset creation guidance
• 3D favicons have been proposed as a W3C Standard
• We recommend using the glTF 2.0 file type
