GLB 3D Format

GLB Converter

GL Transmission Format Binary (GLB) is a compact 3D file format developed by the Khronos Group, the same organisation behind OpenGL and WebGL. It’s the binary version of the GLTF (GL Transmission Format) file, designed to be a universal standard for efficient 3D model transmission and rendering. GLB files can store full 3D scenes—including geometry, textures, materials, animations, and even scene hierarchy—in a single, portable package.

Unlike other formats that require external texture or material files, GLB bundles everything together, making it lightweight and easy to share without losing linked assets. Because it is highly optimized for web and mobile, GLB has become a popular choice for online 3D viewing, augmented reality (AR), and virtual reality (VR) applications.

You can open and edit GLB files in a wide range of software, including Blender, Microsoft 3D Viewer, and Autodesk’s 3ds Max (with plugins). They’re also widely supported by web frameworks like three.js and Babylon.js, making them an ideal format for 3D models on websites and apps. GLB is now considered one of the most modern and versatile 3D file types, especially for developers and designers looking to deliver interactive 3D content with speed and efficiency.

STL 3D Format

STL Converter

The Stereolithography (STL) format is one of the oldest and most widely used 3D formats. Primarily used for 3D printing, it is supported by virtually every 3D printing and slicing program, making it a popular choice for general 3D printing needs. If you’re unsure of a format to use for printing, STL is a safe bet until you know exactly what you want.

You can open STL files in Blender, MeshLab, Fusion360 and many other programs, and the format works across Windows, macOS, Linux, and even mobile platforms. If you want to store material or colour data in your file, however, you may need to look for an STL alternative, as this format only supports geometry data. For mocking up quick prototypes, though, you can’t get much better than STL, with its minimalism and near-universal support.
