Free Online GLTF to GLB Converter

Free online GLTF to GLB converter. Convert your GLTF files to GLB format instantly in your browser. No software installation required.

Convert GLTF to GLB locally in your browser without installing software or creating an account. Your source file stays on your device throughout the conversion. You can make unlimited conversions, with a maximum source-file size of 50 MB. The output contains the mesh and scene data supported by GLB, so review the converted file in your target software before using it in a production workflow.

GLTF and GLB are two variants of the same format - GLTF is JSON-based with external file references, while GLB is a single binary file with everything embedded. Converting GLTF to GLB packages your 3D scene into one compact file that's easier to share, deploy, and load in web applications. Our GLTF to GLB converter combines your GLTF file with its referenced assets into a single, optimized GLB file. The GLTF to GLB conversion is essential for deploying 3D content on the web, mobile apps, and platforms that prefer single-file assets.

How to Convert GLTF to GLB

1

Choose Your GLTF File

Choose the file area or drag and drop your GLTF file to begin. Files up to 50 MB are processed locally in your browser and are never sent to a server.

2

Convert GLTF to GLB

Click the Convert button to read the supported data in your GLTF file and export it in GLB format. Processing time depends on the file size, mesh complexity, and available browser memory.

3

Download Your GLB File

When conversion finishes, download the new GLB file to your device. Open it in your target software to review the geometry, scale, materials, and other format-dependent data before continuing your workflow.

Format Comparison

GLTF

GL Transmission Format

GLTF is an open standard for 3D scenes and models. It supports meshes, materials, textures, animations, and scene hierarchy. GLTF is widely adopted for web-based 3D content.

  • JSON-based format
  • External file references
  • Human-readable
  • Easy to edit
  • Multiple files
GLB

Binary glTF

GLB is the binary version of glTF, a compact and efficient format for 3D models. GLB files contain all textures and data in a single file, making them perfect for web delivery and real-time applications.

  • Binary format
  • Single file
  • Faster loading
  • Smaller size
  • Easy to share
