Free Online GLTF Viewer

View any GLTF file in 3D with full materials and textures. Works in your browser.

GLTF (GL Transmission Format) is the "JPEG of 3D" — an open standard for 3D models on the web, in AR, and in real-time applications. Both the JSON form (.gltf) and the binary form (.glb) are fully supported.

GeometryViewer renders GLTF scenes with full PBR shading: base colour, roughness, metalness, and normal maps all display correctly. AR is available on iPhone via Apple Quick Look and on Android via WebXR in Chrome or Edge.
