What you can do
Fix the scale
GLB is in metres. Scale a millimetre STL by 0.001 if your viewer expects real size.
Lighten it
Decimate dense scans so the GLB loads fast.
Smooth shading
Switch between smooth and flat shading for the look you want.
Split parts
Separate loose parts so each can have its own material.
One-file GLB
Everything, including textures, is packed into one file.

Frequently asked questions
Why convert STL to GLB?
GLB loads natively in web 3D viewers, AR and game engines, and it can carry materials, which STL cannot.
Will the GLB be the right size?
GLB uses metres. A 40 mm STL part opens as 40 units, so scale by 0.001 if you need real-world size.
