Understanding FBX and GLB Formats

Learn about these popular 3D file formats and why you might need to convert between them.

FBX

What is FBX Format?

FBX (Filmbox) is an Autodesk proprietary format widely used in game development, film production, and motion capture workflows. It supports complex animations, skeletal rigs, blend shapes, and multi-material meshes. FBX is the industry standard for transferring animated 3D assets between software like Maya, 3ds Max, and game engines.

GLB

What is GLB Format?

GLB (GL Binary) is a binary format that packages all 3D assets -- geometry, materials, textures, and animations -- into a single compact file. Developed as part of the glTF specification by the Khronos Group, GLB is optimized for web delivery, AR/VR applications, and real-time rendering. Its single-file architecture eliminates dependency issues and ensures consistent loading across platforms.

Why Convert FBX to GLB?

Convert FBX to GLB for lightweight web delivery. GLB provides a compact binary format optimized for browsers, WebGL viewers, and AR experiences.

File Size Comparison

File size differences between FBX and GLB depend on model complexity and the data each format stores. Our converter optimizes the output for the target format while preserving all supported features.
