About This Tool
GLTF files often reference external textures, buffers, and other resources scattered across multiple files. Converting to GLB bundles everything — geometry, textures, materials, and animations — into one self-contained binary file that is simpler to deploy and loads faster on the web.

Frequently Asked Questions
What is the advantage of GLB over GLTF?
GLB is the binary packaging of GLTF. It combines the JSON descriptor, binary buffer, and all external images into a single file. This means fewer HTTP requests, smaller total size, and easier file management for web applications.
Will GLTF shader extensions be preserved?
Standard GLTF extensions (e.g., KHR_materials_unlit, KHR_texture_transform) are preserved in the GLB output. Custom shaders or non-standard extensions may not render correctly in all viewers.
Will the GLB work on all platforms?
GLB is an open standard by the Khronos Group, natively supported by Three.js, Babylon.js, Facebook, Google, and other major platforms. Virtually all modern browsers and 3D viewers can load GLB files.
What happens to multiple .bin files in GLTF?
GLTF may reference multiple external .bin files for mesh and animation data. During GLB conversion, all .bin contents are merged into the single binary chunk inside the GLB, eliminating the need to manage multiple files.
