FAQ
Does this upload my 3D models to a server? No. Just like our image tools, conversion is computed client-side using JavaScript. Your files never leave your computer.
Can I drop embedded GLTF files? Yes. If your `.gltf` has self-contained base64 data URIs for buffers and textures, you can drop it by itself and it converts instantly.
Why should I pack GLTF to GLB? GLB is a single binary file. It is much easier to share, upload, and load in games or viewers compared to a folder containing a `.gltf` and multiple external assets.
