Questions

How do I convert GLTF to GLB?

Drop your GLTF file on this page, or choose it. Anyfile converts it on your device in a moment and the GLB downloads straight away. To change it first, open it in the 3D viewer.

Is my GLTF file uploaded anywhere?

No. The file is read and converted by your own browser, and nothing is sent to a server. You can check: open your browser’s developer tools, go to Network, and convert a file. No upload appears.

Will the animation still play?

Yes. Every frame and its timing are kept in the GLB.

Can I convert several GLTF files at once?

Yes. Drop them together and you get one ZIP with every GLB inside.
