FBX is Autodesk's world; GLB is the web's. This converter moves a mesh from one to the other in your browser — free, anonymous, and with no upload — so an engine asset can finally be viewed in a link.
Three steps, one page, no account. The whole conversion is a local operation — the slowest part is you finding the file.
Drag the file onto the box above. It is read straight off your disk with the browser's File API — no upload, and no progress bar to a server.
The file is parsed, every mesh is baked into world space, and the result is written out in the target format. Your CPU does the work, so a client's unreleased model never leaves the room.
Save the converted file and open it wherever you were headed. Nothing is watermarked and nothing expires.
They solve different problems, which is exactly why one direction of this conversion costs you something and the other does not.
FBX is Autodesk's interchange format and the default currency between Maya, 3ds Max, Unity and Unreal. It carries meshes, materials, rigs and animation, but it is proprietary and a poor fit for the open web.
GLB is the binary flavour of glTF — one file carrying geometry, UV coordinates, materials, textures and a scene graph together. It is what the web, Blender, Unity, Unreal and Three.js all read natively, and it is what this site's generator hands you.
Every conversion is a trade. Any tool that tells you otherwise is lying to you, so here is the exact ledger before you commit.
GLB is the format to keep. It holds geometry and texture in one file and every modern engine reads it, which is why the generator on this page outputs it. Convert onwards whenever a slicer or an older pipeline needs something else.
Convert when the file has to leave the DCC ecosystem. FBX is proprietary and no browser reads it, so anything headed for the web, a viewer or AR has to become glTF first.
The static mesh comes across, along with whatever material the FBX had embedded; rigs and animation do not — the scene is exported in the pose it loaded in. Inspect it in the viewer to confirm what survived before you rebuild anything.
You do not have to go back to the home page. Type a prompt or drop an image, and take the .glb — free, anonymous, no watermark.
No. The converter exports the static scene, so a rigged or animated FBX arrives as a single frozen mesh. Keep the FBX for the animation work and use the GLB as the thing you show people.
No. FBX is a proprietary Autodesk format and this converter reads it but cannot write it. For the other direction, use Blender — it imports GLB and exports FBX, and it is free.
Same converter, same rules: free, in your browser, no signup.
3D AI Studio generates the .glb too — free, anonymous, no watermark.
No signup, no upload, no watermark — and the converter does not care how big the file is.
