What is GLTF/GLB?

glTF (GL Transmission Format) is an open standard developed by the Khronos Group for efficient transmission and loading of 3D scenes and models. Often called the 'JPEG of 3D', glTF is designed to minimize file size and runtime processing, making it the preferred format for web and real-time 3D applications.

The format comes in two variants: glTF uses a JSON-based structure with external binary buffers and texture files, while GLB packages everything into a single binary file for easier distribution. Both variants support meshes, materials, textures, animations, skeletal rigs, morph targets, and scene hierarchies.

glTF has rapidly become the de facto standard for web-based 3D content. It is supported by Three.js, Babylon.js, Unity, Unreal Engine, Blender, and all major web browsers through WebGL and WebGPU. Its efficient binary data layout and PBR material model make it ideal for interactive experiences, AR/VR applications, and e-commerce product configurators.

How to View GLTF/GLB Files Online

1

Upload Your GLTF/GLB File

Drag and drop your .gltf .glb file onto the viewer above, or click the upload area to browse your device. The file loads instantly in your browser.

2

Interact with Your Model

Rotate, pan, and zoom to inspect every detail of your 3D model. Toggle wireframe view and use measurement tools to check geometry.

3

Export or Share

Take screenshots, toggle view modes, or share your model. All processing happens locally in your browser for complete privacy.

GLTF/GLB Viewer Features

PBR Material Rendering

glTF uses a physically based rendering material model for realistic metallic-roughness surfaces in the viewer.

Animation Playback

View skeletal animations, morph targets, and keyframe animations embedded in your glTF and GLB files.

Scene Hierarchy

glTF supports complex scene graphs with multiple meshes, cameras, and lights organized in a node hierarchy.

Optimized for Web

Binary data layout and optional Draco compression make glTF files load and render faster than other 3D formats in browsers.

GLTF/GLB Viewer FAQ

glTF (GL Transmission Format) is an open 3D format developed by the Khronos Group. It efficiently stores meshes, materials, textures, and animations in a compact format optimized for web and real-time applications.
glTF uses a JSON file with separate binary buffers and texture files. GLB packages everything into a single binary file. Both store the same data; GLB is more convenient for distribution since it is a single file.
Yes. Our viewer can play skeletal animations and morph target animations embedded in glTF and GLB files. Use the playback controls to play, pause, and scrub through animation timelines.
glTF is primarily designed for real-time rendering and web applications. For 3D printing, STL or 3MF formats are recommended. You can convert glTF to STL using our tools.
Just as JPEG became the universal standard for 2D images on the web, glTF aims to be the universal standard for 3D content. Its efficient design, broad tool support, and open specification make it ideal for interoperable 3D workflows.
