About the GLB format
GLB is the binary flavor of glTF, the modern standard for 3D on the web: a single file with everything inside. It's mostly used for the web (Three.js, model-viewer), AR, games, online stores, Sketchfab, and it stores geometry, PBR materials, textures, scene hierarchy and animations.
Frequently asked questions
Why is my GLB so heavy?
Almost always the textures: a GLB with four 4K textures can weigh 50+ MB with minimal geometry. The GLB compressor converts them to WebP and applies meshopt — 60–85% reductions are normal.
Does GLB support animations?
Yes: skeletons, morph targets and node animations travel inside the file. This viewer shows the model in a static pose; animations are preserved when you convert or compress.
How do I use a GLB on my website?
With Google's <model-viewer> it's three lines of HTML, or with Three.js for full control. GLB is the native format of both — no prior conversion.
