Convert your 3MF 3D models to GLTF format using our free online tool. Transform 3D Manufacturing Format (3MF) files into GLTF JSON format while maintaining geometry, materials, and animations. No Signup Required.
•3MF (3D Manufacturing Format) was developed by the 3MF Consortium as an industry standard for 3D printing
•GLTF is created by the Khronos Group and is known as the "JPEG of 3D" for web and application usage
•3MF focuses on manufacturing data while GLTF prioritizes visualization and animation
•Converting 3MF to GLTF allows 3D printing models to be easily viewed in web browsers and 3D applications
Technical Insight
Converting 3MF to GLTF involves translating the XML-based 3MF structure into the JSON-based GLTF format with separate buffer files for binary data.
The process extracts mesh data, materials, textures, and other properties from the 3MF container and maps them to the corresponding GLTF structure.
All model information including geometry, materials, textures, and scene hierarchies are preserved during this conversion.
3MF vs GLTF Comparison

Limited web browser support
GLTF Format
JSON-based format (human-readable)
Multiple files (JSON + bin + textures)
Easier to edit and debug
Optimized for web and app visualization
Wide support in browsers and 3D engines
Frequently Asked Questions
Why should I use an online 3MF to GLTF converter?
An online 3MF 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 3MF to GLTF?
No, you won't lose any data when converting from 3MF to GLTF. The conversion preserves all geometry, materials, textures, and other model details from the 3D Manufacturing Format to the GL Transmission Format.
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 3MF 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 3MF file size?
The maximum 3MF file size limit for conversion is 100MB.
