GLB & glTF Viewer
Check a .glb or .gltf model with its PBR materials and textures before you put it on a website, in AR or in a game.

How to use the GLB Viewer
Open the model
Drop a .glb file. For a .gltf, select it together with its .bin file and texture images.
Inspect materials and shape
Orbit around the model to see the base colour, metalness, roughness and normal maps as they will render on the web.
Check the numbers
See the triangle and vertex count, the number of meshes and the model size, or save a PNG preview.
About the GLB Viewer
glTF is the open 3D format from the Khronos Group, often called the “JPEG of 3D”. A .glb is the binary version that packs the geometry, materials and textures into a single file. It is the format of choice for 3D on websites, Android AR (Scene Viewer), Meta and other VR headsets, Shopify and Facebook 3D posts, and it is the default export in Blender and Sketchfab.
Because glTF uses physically based rendering (PBR), the same model should look the same in every glTF viewer. That makes this page a quick way to check an export: whether the textures came along, whether the scale is sensible and whether the triangle count is light enough for mobile.
Frequently asked questions
What is the difference between GLB and glTF?
They hold the same data. A .gltf is a JSON file that refers to separate .bin and image files; a .glb packs everything into one binary file, which is easier to share.
Does the viewer play animations?
Not yet. Animated models are shown in their default pose so you can check geometry and materials.
Can I view GLB files on iPhone?
Yes, the viewer works in Safari on iOS. Note that Apple’s AR Quick Look itself uses USDZ, not GLB.
Is my model uploaded?
No. The GLB is parsed and rendered with WebGL on your device, so unreleased products and game assets stay private.
