GLB viewer

GLB files carry their materials and textures inside, so they look in this viewer much as they will in a game engine or on a web page. It's a quick way to check a model from a library or an AI generator.

Tips for better results

  • Embedded-texture glTF files open fine; ones that reference separate files don't.
  • Check the triangle count before putting a model on a web page.

Checking a GLB before you use it

  • Check the materials look right: missing textures usually mean the file references external images.
  • Look at the size: GLB uses metres, so a 2-unit-tall character is 2 m.
  • Count meshes: dozens of small meshes are slow in engines and worth merging.
  • Inspect the triangle count before putting it on a web page.
