Convert your GLB 3D models to GLTF format using our free online tool. Transform glTF Binary (GLB) files into GLTF JSON format while maintaining geometry, materials, and animations. No Signup Required.
•GLTF and GLB are both created by the Khronos Group, with GLB being the binary version of GLTF
•GLB efficiently packages all assets into a single binary file, while GLTF uses JSON with external resources
•GLTF stands for "GL Transmission Format" and is often called the "JPEG of 3D"
•Converting GLB to GLTF makes the 3D data human-readable and easier to edit
Technical Insight
Converting GLB to GLTF involves unpacking the binary container and converting it into a JSON structure with separate buffer files for binary data.
The process extracts the JSON chunk and buffer data from the GLB container and organizes them into the GLTF structure.
All model information including geometry, materials, textures, animations, and scene hierarchies are preserved during this conversion.
GLB vs GLTF Comparison
GLB Format
Binary format (smaller file size)
Self-contained single file
Faster loading for applications
Efficient for web applications
Not human-readable or easily editable
GLTF Format
JSON-based format (human-readable)
Multiple files (JSON + bin + textures)
Easier to edit and debug
Better for development workflows
Larger total file size than GLB
Frequently Asked Questions
Why should I use an online GLB to GLTF converter?
An online GLB to GLTF converter allows you to quickly transform 3D models between formats without installing specialized software. It's convenient for converting models from any device with a browser.
Will I lose geometry or materials when converting GLB to GLTF?
No, you won't lose any data when converting from GLB to GLTF. GLTF is the human-readable JSON form of GLB, which is the binary version. The conversion preserves all geometry, materials, textures, and animations.
How long does the conversion process take?
Conversion time depends on the model size and complexity. Most conversions complete within a few minutes.
Is my model data secure when using this converter?
Yes, we prioritize your privacy. Your files are securely stored on our servers and automatically deleted after 24 hours to ensure complete privacy and security.
Is this tool free to use?
Yes, our GLB to GLTF converter is completely free to use without any hidden charges. You just need to create an account to get started.
How long do you store our data?
Your model data is temporarily stored on our secure servers and automatically deleted after 24 hours for your convenience and privacy.
What is the limit of GLB file size?
The maximum GLB file size limit for conversion is 100MB.
