Open and view GLB / glTF files online — free, no signup, no upload
glTF (GL Transmission Format) is the modern standard for real-time 3D and the web. .glb is its single-file binary version, bundling geometry, materials and textures together. This viewer opens GLB / glTF files right in your browser so you can rotate, zoom and pan a model and check its bounding-box dimensions and triangle count — without installing software or sending your file anywhere.
How to view a GLB / glTF file
1. Drag your file onto the box above, or click Open GLB / glTF file. 2. Drag to orbit, scroll to zoom, right-drag to pan. 3. Read the width/depth/height and triangle count in the panel.
Frequently asked questions
How do I open a GLB or glTF file online?
Drag your .glb or .gltf onto this page or click Open File — it renders instantly in your browser. Nothing is uploaded.
What's the difference between GLB and glTF?
They're the same format: .gltf is JSON (sometimes with separate .bin/texture files), while .glb packs everything into one binary file. This viewer opens both.
Is my model uploaded?
No — it's read and rendered entirely on your device, so nothing leaves your computer.
Does it show textures and materials?
Embedded materials and textures in a .glb load with the model. External resources referenced by a .gltf may not resolve, but the geometry always shows.
