how to convert fbx to gltf
Drop your FBX file
Drag your FBX file into the drop zone above, or click the box to pick a file from your computer or phone. The browser reads the file directly — nothing uploads.
Click Convert
The page runs three.js on your device to decode the Filmbox and encode it as GL Transmission Format. Most conversions finish in a few seconds; large or codec-heavy files (RAW, video) can take longer.
Download the GLTF file
When the conversion finishes, the GLTF file is ready to download. Save it anywhere on your device.
FAQ
common questions
Why convert FBX to glTF?
glTF is the modern standard for 3D content delivery — designed specifically for runtime use in web apps, game engines, and AR/VR. FBX is the industry standard for authoring (Maya / 3ds Max / Blender all export FBX), but it's bigger, slower to load, and not great for web deployment. Converting bridges the gap: author in FBX, ship in glTF.
Will my animations, materials, and textures survive?
Most of them. glTF supports skeletal animations, blend shapes, PBR materials, textures, and scene hierarchy — the converter maps FBX content into glTF equivalents. Some FBX-specific extras (proprietary Maya / 3ds Max features, exotic deformers) may not have glTF equivalents and get simplified. For most game / web 3D workflows, the conversion is faithful.
Should I pick glTF (.gltf) or GLB (.glb)?
GLB by default. GLB packages everything (geometry, materials, textures, animations) into one binary file — easier to share and load. .gltf is a JSON file that references separate .bin and texture files, useful if you want to inspect or edit the JSON. For runtime use (web, games, AR), GLB is almost always the right choice.
Will the glTF be smaller than the FBX?
Usually similar or slightly larger. FBX is reasonably efficient; glTF / GLB produce comparable sizes for the same content. Where glTF wins is in runtime loading speed — its binary layout matches what GPUs want directly, so loading is much faster even if file size is similar.
Where will I use the converted glTF?
Three Js / Babylon Js / Unity / Unreal Engine all import glTF cleanly. Web 3D viewers (Sketchfab, model-viewer, scene-viewer) expect glTF / GLB. AR/VR systems (ARKit, ARCore, WebXR) prefer glTF. If you're loading 3D content in any modern runtime environment, glTF is what you want.
