Convert your GLB 3D models to OFF format using our free online tool. Transform glTF Binary (GLB) files into OFF format while maintaining geometry and vertex structure. 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
•OFF (Object File Format) is a simple geometry-focused format used in computer graphics
•Converting to OFF is particularly useful for research, academic applications, and specialized 3D tools
Technical Insight
Converting GLB to OFF involves extracting 3D geometry from the binary container and transforming it into the simple, text-based OFF format.
The process requires parsing binary structures to access JSON metadata and buffers containing vertex data, normals, and face indices.
While geometry is preserved, OFF format focuses solely on vertices and faces, so materials, textures, and animations from the GLB file won't be transferred.

Frequently Asked Questions
Why should I use an online GLB to OFF converter?
An online GLB to OFF 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 OFF?
Our converter maintains the original geometry and vertex structure. The OFF format primarily stores geometric data, so material properties and textures from the original GLB won't be transferred.
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 OFF 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.
