glTF File Format

glTF JSON Model category

glTF (JSON form) is the human-readable sibling of GLB: the same scene, meshes and PBR materials, but stored as JSON with separate binary and texture files.

Typical use: Convert .gltf to GLB when you need one portable file, or to OBJ/STL for tools and 3D printers that expect those.

About the glTF format

glTF in its JSON form (.gltf) is the readable side of the glTF 2.0 family: scene graph, meshes, materials, cameras and animations described in JSON, with binary geometry in a separate .bin buffer and textures as their own image files. Seeing the structure as text is genuinely useful when you are debugging an asset pipeline or hand-editing a material.

The trade-off is portability: a .gltf is only self-contained when its buffers are embedded as data URIs, which bloats the file. Everywhere you just want to ship or drop a model into a viewer, GLB is the better answer — and that is exactly what the gltf-to-glb page does for you, in your browser, without uploading the model.

Strengths

✓ Human-readable JSON structure
✓ Same PBR materials and scene data as GLB
✓ Easy to diff, debug and hand-edit

Limitations

✗ Usually needs separate .bin and texture files
✗ Breaks when files are moved apart
✗ Larger than GLB once buffers are embedded

Structure: JSON scene + external buffer
Materials: PBR, textures as separate files
Compatibility: All glTF loaders
Best for: Editing and debugging assets
