Convert FBX to GLB
Free · no signup · no watermark · runs in your browser · batch up to 20 files, download as ZIP
Loading the 3D converter…
FBX is how characters and animations leave Maya, 3ds Max and Mixamo, and GLB is what the web, three.js, Babylon.js, model-viewer, Godot and Android AR want. This converter reads the FBX in your browser, shows it with its animations so you can check them before converting, and writes a single GLB with meshes, skeleton, animation clips and materials converted to PBR.
This conversion runs entirely in your browser. The file is never uploaded, which makes it instant, private and usable on work files you would not want to send to a stranger's server.
It also works as a bulk FBX to GLB converter: drop up to 20 FBX files at once, they are converted one after another in your browser, and you can download each file on its own or all of them together in a single ZIP. A file that fails is listed with the reason and does not stop the rest of the batch.
How to convert FBX to GLB
- Drop your FBX files onto the box above, or click it to choose from your computer. Up to 20 at once.
- Check the 3D preview and model info. If the model is the wrong size or lying on its back, open the options to set the source units or rotate Z-up to Y-up, then press Convert.
- Download each converted file from the list, or press "Download all (.zip)" to get the whole batch in one ZIP file.
What changes when you convert FBX to GLB
GLB can hold everything FBX can and more: meshes, PBR materials, textures, skeletons and animation.
FBX is a closed format read here by an open-source parser: geometry is reliable, while complex materials, some embedded textures and unusual animation setups may not convert. Check the preview before you download.

FBX: Autodesk's proprietary interchange format, used by Maya, 3ds Max, Unity, Unreal and Mixamo for characters and animation. Browsers can read it on a best-effort basis but cannot write it.
GLB: The single-file binary form of glTF, the Khronos standard for 3D on the web, in game engines and in Android AR. Holds meshes, PBR materials, textures, skins and animation, in metres, Y-up.

Can I convert multiple FBX files to GLB at once?
Yes, up to 20 files in one go. Drop or select them all together and they are converted one after another.
