What is a .glTF file?
glTF is a modern, efficient 3D model format for real-time graphics and the web.
- Did you know
- glTF was released by the Khronos Group in 2015 and is often called "the JPEG of 3D".
- glTF stands for GL Transmission Format, designed by the Khronos Group as an efficient way to deliver 3D scenes to graphics applications and the web.
- glTF 2.0 became international standard ISO/IEC 12113 in 2022, and the format is widely nicknamed “the JPEG of 3D”.
- As 3d / printing
- 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.
- As 3d / cad / point clouds (more)
- Header and metadata extraction for 3D meshes, voxels, BIM, point clouds and Gaussian splats: Wavefront OBJ, Stanford PLY, OFF, glTF, AMF, MagicaVoxel VOX, COLLADA DAE/ZAE, USD crate, X3D/VRML, LightWave LWO/LWS, Quake MD2/MD3/MDL, VRM avatars, Siemens JT, LAS/LAZ/PCD/PTS/E57 LiDAR clouds, IFC BIM, and .splat/.spz - vertex/face/point counts, bounding boxes, units and authoring tool.
- Depth of analysis
- .glTF 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 .glTF file
- Drag a .glTF 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.
