View GLTF and GLB files instantly in your browser with our free online GLTF viewer. Optimized for web 3D. No downloads required.
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.
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.
Rotate, pan, and zoom to inspect every detail of your 3D model. Toggle wireframe view and use measurement tools to check geometry.
Take screenshots, toggle view modes, or share your model. All processing happens locally in your browser for complete privacy.
glTF uses a physically based rendering material model for realistic metallic-roughness surfaces in the viewer.
View skeletal animations, morph targets, and keyframe animations embedded in your glTF and GLB files.
glTF supports complex scene graphs with multiple meshes, cameras, and lights organized in a node hierarchy.
Binary data layout and optional Draco compression make glTF files load and render faster than other 3D formats in browsers.
