glTF

GL Transmission Format

glTF is the "JPEG of 3D" — a JSON scene description with PBR materials, animation and skinning, designed to be loaded straight onto the GPU. The .gltf variant keeps buffers and textures as separate side-car files.

Extension: .gltf
MIME type: model/gltf+json

01 Convert glTF to something else

glTF to GLB A repackage, not a conversion. Materials and animation survive.

02 Convert something else to glTF

Opening a .gltf file

If you landed here because something handed you a .gltf file and nothing on your machine will open it, converting it to a format you already have a reader for is usually faster than installing new software. Every conversion above runs in this browser — the file is not uploaded, so it works on a locked-down work machine and on a file you are not allowed to send anywhere.
