How to convert glTF to STL

  1. Select the .gltf and its .bin file together (or a single .glb) and drop them above.
  2. Check the size under the view; glTF is in metres.
  3. Keep STL selected and download.

Texture images next to the .gltf are not needed — STL keeps geometry only. If the .bin is missing, the converter tells you which file it needs.

What is the difference between .gltf and .glb?

Same format: .gltf is JSON with separate .bin and image files, .glb packs everything into one binary file.

Is my model uploaded?

No. It is converted in your browser.
