About the glTF Format
The glTF (GL Transmission Format) is an open standard developed by the Khronos Group for the efficient transmission and loading of 3D scenes and models. Often referred to as the 'JPEG of 3D', glTF is designed to be a universal format that bridges the gap between 3D content creation tools and modern rendering engines.
Unlike its binary counterpart GLB, a glTF asset typically consists of a JSON file describing the scene structure, plus external binary (.bin) files for geometry data and separate image files for textures. This multi-file structure makes glTF especially convenient for developers who need to inspect, edit, or programmatically modify individual parts of a 3D scene.
glTF 2.0 supports physically based rendering (PBR) materials, skeletal animation, morph targets, and a rich ecosystem of extensions. It is the format of choice for web-based 3D applications, game engines like Unity and Unreal, and AR/VR platforms.

Quick Guide
How to View glTF Files Online
Upload your file
Drag and drop your .gltf 3D model file into the dropzone above, or click the upload button to select a file from your device.
Instant Rendering
Our viewer processes the glTF file locally in your browser. Wait a few seconds for the geometry and textures to load.
Interact & View
Use your mouse or touch screen to rotate, pan, and zoom the 3D model. If the glTF file has animations, they will start automatically.

Frequently Asked Questions
What is a glTF file?
glTF (GL Transmission Format) is an open standard JSON-based 3D file format. It describes 3D scenes including meshes, materials, textures, and animations, and is often accompanied by separate .bin and image files.
How is glTF different from GLB?
glTF uses a JSON file with separate binary and texture files, while GLB packages everything into a single binary file. glTF is better for editing and development, while GLB is better for sharing and deployment.
Can I view animated glTF files?
Yes, our glTF viewer fully supports skeletal animations, morph targets, and other animation types defined in glTF 2.0.
Do I need to upload all files (.gltf, .bin, textures)?
For the best results, you should upload the .gltf file along with its referenced .bin and texture files. Some glTF files embed data inline using data URIs and only require the single .gltf file.
