Autodesk's 3D interchange format, carrying character rigging and animation data. It is the de facto standard in game development.
FBX to GLTF Converter
Convert FBX files to GLTF free in your browser — no signup, no install, and the file is never uploaded to a server. GLTF keeps full quality with no further loss.
What changes in this conversion
- GLTF is a newer format — check that the software or device you are sending it to supports it before switching.
- The geometry (vertices and faces) is converted exactly. Material, texture and animation data is only carried over when both formats support it — GLTF keeps what it can and drops the rest.
How to use
-
Add your FBX file
Drag the FBX file onto the drop area above, or click it to pick a file from your device. You can add several files at once.
-
Confirm GLTF as the output
GLTF is already selected as the output format on this page. This format converts straight through with no extra settings.
-
Run the conversion
Press the convert button. Processing happens on your own device, so the time depends on your computer rather than a server queue.
-
Download the GLTF file
When it finishes, download the GLTF file. Converting multiple files gives you the option to download them together as a ZIP.
About these formats
The JSON text version of GLB, letting you inspect and edit the structure directly. Textures are usually kept as separate files.
Frequently asked questions
Is converting FBX to GLTF really free?
Yes. FBX to GLTF conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.
Are my FBX files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so the FBX file never leaves your device. That is also why it works without an internet connection once the page has loaded.
Will the GLTF file open everywhere?
GLTF is a newer format. Current browsers and phones handle it, but older desktop software may not — keep the original FBX if you have to send it to someone on an old machine.
Does the GLTF file get bigger than the FBX?
It can go either way. Both formats are lossless, so nothing is thrown away — the size difference comes from how each one packs the same data.
Is there a file size limit for FBX to GLTF conversion?
The free plan handles files up to 200MB. Because processing happens on your own device, very large files depend on your computer's memory rather than a server quota.
