Convert glTF to GLB

glTF → GLB: what you should know

glTF is the open Khronos standard for 3D scenes, in its JSON-with-resources variant. It's used mostly in the web, AR/VR, game engines, asset pipelines, and it stores geometry, PBR materials, textures, scene and animations. GLB, on the other hand, is the binary flavor of glTF, the modern standard for 3D on the web: a single file with everything inside — the format expected by the web (Three.js, model-viewer), AR, games, online stores, Sketchfab.

This tool converts your glTF files to GLB right in the browser: no queue, no artificial size limit and, above all, your file is never uploaded to any server. Geometry is preserved with the exact coordinates and scale of the original — important if the model is going to be printed or measured.

Keep in mind: The static scene is converted: animations aren't preserved. If you need to keep that data, convert to a format that supports it (GLB keeps materials and textures; PLY keeps vertex colors).
