Convert your OFF 3D models to GLTF format using our free online tool. Transform Object File Format (OFF) files into GLTF JSON format while maintaining geometry, materials, and textures. No Signup Required.
•OFF (Object File Format) is a simple format for representing 3D geometry, particularly useful for academic and mathematical applications
•GLTF is created by the Khronos Group and is known as the "JPEG of 3D" for web and application usage
•OFF files store vertices and faces in a simple text format, making them easy to read but limited in features compared to GLTF
•Converting OFF to GLTF allows mathematical and academic 3D models to be easily viewed in modern web browsers and game engines
Technical Insight
Converting OFF to GLTF involves translating the plain-text OFF structure into the JSON-based GLTF format with binary buffer files for geometry data.
The process extracts vertices, faces, and optionally colors from the OFF file and maps them to the corresponding GLTF structure.
During conversion, the geometry is optimized and embedded within the GLTF file, making the model more web-friendly and compatible with modern 3D engines.
OFF vs GLTF Comparison
OFF Format

Wide support in browsers and 3D engines
Frequently Asked Questions
Why should I use an online OFF to GLTF converter?
An online OFF 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 OFF to GLTF?
No, you won't lose any data when converting from OFF to GLTF. The conversion preserves all geometry, materials, textures, and other model details from the Object File Format (OFF) 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 OFF to GLTF converter is completely free to use without any hidden charges. You can convert your 3D models instantly without any limits.
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 OFF file size?
The maximum OFF file size limit for conversion is 100MB.
