What is GLTF?
glTF (GL Transmission Format) is the open standard for 3D assets on the web, developed by the Khronos Group. A glTF scene consists of a .gltf JSON file, one or more .bin files with geometry data, and separate texture image files. GLB is the binary version that bundles everything into one file.
Who uses GLTF?
Used across the web, game engines (Unity, Unreal, Godot), 3D tools (Blender, 3ds Max, Maya), e-commerce platforms, AR/VR applications, and any workflow that targets web-based 3D rendering.
Why convert GLTF to GLB?
Separate glTF files (.gltf + .bin + textures) are fragile — missing one file breaks the model. Converting to GLB packs everything into a single binary file that is easier to share, upload, and embed. No file size penalty — GLB is just a container.
How it works
Drop your .gltf file
Drag and drop or click to select your GLTF model.
Auto-convert & optimize
Trice converts GLTF to GLB and applies meshopt compression — all in your browser.

Frequently asked questions
They are the same format. glTF uses separate files (JSON descriptor + binary data + textures), while GLB bundles everything into a single binary file. GLB is more convenient for sharing and embedding.
No. GLB is a lossless container — it packs the exact same data into one file. Geometry, materials, textures, and animations are identical.
Put the .gltf, .bin, and all texture files into a ZIP archive, then drop the ZIP here. Trice will resolve all file references and embed them into the GLB.
No. GLB is typically the same size or slightly smaller than the combined glTF files. With meshopt compression applied during conversion, the output is often 20-40% smaller.
