GLTF (GL Transmission Format) is a modern, efficient file format for 3D models developed by the Khronos Group. Often called the "JPEG of 3D," it's designed for efficient transmission and loading of 3D scenes and models.
GLB is the binary version of GLTF that packages all assets (including textures) into a single file, making it more convenient for distribution.
The format is widely supported across the 3D industry, including game engines, AR/VR platforms, web applications, and 3D modeling software, making it ideal for cross-platform 3D content delivery.
GLTF was first introduced in 2015 by the Khronos Group, the same consortium behind other important graphics standards like OpenGL and Vulkan.
The format was specifically designed to be efficient for web-based 3D applications, which is why it's widely used in WebXR experiences, 3D product visualizations, and online configurators.
GLTF 2.0, released in 2017, introduced significant improvements including physically-based rendering (PBR) materials that allow for realistic surface appearances.
Major companies like Microsoft, Google, Facebook, and Amazon all support GLTF in their 3D and AR platforms, making it the de facto standard for shareable 3D content.
NASA's Perseverance Mars rover mission makes 3D models available in GLTF format, allowing anyone to explore Martian artifacts in detail through their browser.
What makes GLTF technically superior is its JSON-based structure (for .gltf files) that allows both human readability and machine parsing efficiency. Binary data for meshes, animations, and textures is stored separately for optimal loading.
GLB files, on the other hand, use a binary container format that packages the JSON description and all binary data together, making file handling simpler.
Unlike older formats, GLTF directly supports modern rendering techniques like Physically Based Rendering (PBR), which simulates realistic material properties based on physical principles of light interaction.
The format includes compression options like Draco (for mesh compression) and Basis Universal (for texture compression), which can reduce file sizes by up to 90% while maintaining visual quality.
GLTF's extensibility system allows developers to add custom properties and features while maintaining compatibility, making it extremely flexible for specialized applications.
Our GLTF Viewer allows you to upload and view 3D models in GLTF or GLB format directly in your browser. You can rotate, zoom, and inspect models from all angles without needing specialized software.
GLTF (GL Transmission Format) is a modern 3D file format that efficiently stores 3D model data including geometry, materials, textures, animations, and more. GLB is the binary version of GLTF that packages all assets into a single file. Both formats are developed by Khronos Group and are considered the 'JPEG of 3D'.
Simply upload your GLTF or GLB file using the upload button, and the 3D model will appear in the viewer. You can then use your mouse to rotate the model, scroll to zoom in/out, and right-click and drag to pan the view.
The viewer supports GLTF and GLB files up to 50MB in size. Larger files may take longer to load depending on your internet connection speed.
Yes, your 3D models are processed entirely in your browser. We never upload or store your models on our servers, ensuring complete privacy and security of your intellectual property.
The GLTF Viewer is designed for viewing only. It doesn't currently support exporting to other formats or downloading modified versions of the models.
The GLTF Viewer works best on modern browsers like Chrome, Firefox, Edge, and Safari. Make sure your browser is updated to the latest version for optimal performance.
Yes, GLTF/GLB files are self-contained and include textures, materials, and animations. GLB files are particularly convenient as they package all assets into a single binary file.
