Converting glTF Binary (GLB) to glTF

GLB and glTF are the same format in two packages: GLB is a single binary, glTF is human-readable JSON. Converting GLB to glTF unpacks the binary into text you can inspect, diff or tweak by hand.

What's kept and what's dropped

Geometry, materials and animation are preserved — only the packaging changes from binary to JSON. Buffers and textures are embedded, so you still get a single, self-contained .gltf file.
