Convert your GLB 3D models to 3MF format using our free online tool. Transform glTF Binary (GLB) files into 3MF format while maintaining geometry and material properties. No Signup Required.
•GLB format was developed by the Khronos Group in 2015 as a binary container for glTF
•GLB efficiently packages all assets (models, textures, animations) into a single binary file
•3MF (3D Manufacturing Format) was developed by the 3MF Consortium to standardize 3D printing formats
•Converting to 3MF is particularly useful for 3D printing applications and manufacturing workflows
Technical Insight
Converting GLB to 3MF involves extracting 3D geometry from the binary container and transforming it into the XML-based 3MF format.
The process maintains texture coordinates, materials, and colors while optimizing the model for manufacturing applications.
3MF format can preserve most of the visual properties of your GLB model while adding manufacturing-specific features like print tickets and production information.

Frequently Asked Questions
Why should I use an online GLB to 3MF converter?
An online GLB to 3MF 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 3MF?
Our converter maintains the original geometry and material properties. 3MF is a modern format that can preserve most of the features from your GLB model, including colors and textures.
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 3MF 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.
