Convert your STL 3D models to GLB format using our free online tool. Transform Standard Triangle Language (STL) files into glTF Binary (GLB) format while maintaining geometry and materials. No Signup Required.
The STL format (Standard Triangle Language or STereoLithography) was developed by 3D Systems in the late 1980s and is one of the most common file formats for 3D printing.
STL files describe only the surface geometry of a 3D object without any representation of color, texture, or other attributes common to other 3D file formats.
GLB (glTF Binary) is a binary file format based on glTF (GL Transmission Format) that efficiently packages 3D model data. It was developed by Khronos Group and is widely used for web-based 3D applications and AR/VR experiences.
This conversion is especially useful when you need to prepare 3D models for web applications, WebXR, AR/VR platforms, and other modern 3D environments that benefit from the optimized format of GLB.
Converting STL to GLB involves transforming the basic geometry information from the STL format into the optimized binary structure of the glTF format.
The process preserves triangle mesh data and face normals, then restructures them into the GLB binary format, which can include additional information like materials, textures, and animations.
Our converter ensures that the model's geometry is accurately represented in the GLB format, ready for use in web applications, AR/VR experiences, and modern 3D visualization platforms.
Converting to GLB offers several advantages: it provides better performance for web-based applications, supports PBR materials, animations, and is highly optimized for modern 3D frameworks like Three.js and Babylon.js.
An online STL to GLB 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.
Our converter maintains the original geometry and basic material properties. The GLB format supports advanced material properties, textures, and scene information, providing more capabilities than the basic STL format.
Conversion time depends on the model size and complexity. Most conversions complete within a few minutes.
