What is a .GLB file?
GLB is the single-file binary version of glTF, bundling geometry, textures and animation together.
- Did you know
- GLB is the packaged form of glTF, the Khronos 3D format released in 2015.
- GLB is the binary container for glTF 2.0, packing a JSON description chunk and a raw binary buffer chunk into one self-contained file.
- glTF 2.0, and with it the GLB packaging, was adopted as international standard ISO/IEC 12113 in 2022.
- What Analyser reads
- Identify 3D and 3D-printing files: FBX, glTF/GLB, USD/USDZ, and Blender (BLEND). OBJ, PLY, OFF, 3MF and AMF get a full 3D viewer - see the 3D model section.
- Depth of analysis
- .GLB is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .GLB file
- Drag a .GLB file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
