GLB and glTF, explained
What is GLB?
GLB is the binary form of glTF, often called "the JPEG of 3D". One file packs the full scene: meshes, PBR materials, embedded textures, animations, and a real unit scale (meters). It is the standard for 3D on the web and the default output of most AI 3D generators.
Because everything is embedded in a single binary file, GLB transfers cleanly between tools with nothing lost in transit. glTF/GLB is an open Khronos standard, loads fast, and is supported by every modern engine, DCC tool, and web viewer.

What is glTF?
glTF is the JSON flavor of the same Khronos standard behind GLB. The scene description is human-readable JSON, typically pointing at external binary buffers and texture images. Same capabilities as GLB - PBR materials, animations, real units - in a multi-file layout.
The multi-file layout makes .gltf convenient to inspect and edit but fragile to share: if the .bin or textures go missing, the file breaks. For distribution, most pipelines pack glTF into single-file GLB - the conversion this fleet does in one click.

What survives the glb to gltf conversion
Format conversion is honest work: some data has nowhere to go in the target format. Here is exactly what carries over.
Scene & geometry
Same glTF 2.0 data, different packaging - nodes, meshes, and transforms carry exactly.
Materials & textures
PBR materials and embedded textures carry over, re-embedded as data URIs inside the JSON.
UVs, normals, vertex colors
All vertex attributes unchanged.
Single-file integrity
The output embeds its buffers - unlike typical .gltf exports, nothing external can go missing.
Animations
Animation clips are not carried in this conversion - unpack animated scenes with gltf-pipeline instead.
When should you convert GLB to glTF?
Unpack to .gltf when you need to see or edit the scene as JSON: tweaking material values by hand, debugging a viewer issue, learning the format, or feeding tools that want the JSON form.
Repack to GLB for shipping - smaller, single-request, and universally loadable. The .gltf form is for humans and tooling, not distribution.

And if what you actually need is a new model rather than a new file format: 3D AI Studio's main tool can generate 3D models from photos with AI - with exports to every format on this page.
