About glTF
GL Transmission Format 2.0
glTF is the JSON flavour of glTF 2.0. The scene description lives in the .gltf file, while geometry sits in a .bin file and textures in images — select them all together.
About GLB
Binary glTF 2.0
GLB is the binary version of glTF 2.0: geometry, PBR materials, textures and animations packed into one file. It is the standard for web 3D, AR and most game engines.
How it works
- 01
Drop the .gltf file (with its textures or .bin/.mtl files, if any).
- 02
Check the model in the 3D preview; GLB is already selected.
- 03
Click “Convert” and the .glb file downloads.
Questions
Is the glTF to GLB converter free?+
Yes, without limits, sign-up or watermark.
Is my glTF file uploaded?+
No. The glTF file is read and converted in your browser; nothing is sent to a server.
Why are textures missing after converting glTF?+
Textures stored as separate files must be selected together with the model. GLB keeps them only if the format supports textures.
