An STL for the web, a game or AR.
Turn an STL into a GLB in your browser, nothing uploaded: the shape at its real size in metres, standing on Y, checked before you download it.

Web pages, game engines and Android's 3D apps take GLB, not STL. KeepSimp turns one into the other in your browser, and gets its size right on the way.
Drop the STL and download the GLB.
Open STL to GLB and drop the .stl on it. The GLB is chosen; press Download GLB.
Before the file is offered, KeepSimp opens it again with its own reader and counts its triangles and measures its size; a file that does not match the model is not offered, and the page says what was wrong.
Say what its numbers mean.
An STL does not say its unit; a GLB is always in metres. The page reads the STL as millimetres, as most are made, and shows the size that gives. If the model looks a thousand times too big or small, choose its unit under Its numbers are in before downloading.
The GLB stands on Y, turned a quarter round from the STL's Z, so it is upright in a viewer or an engine.
How it looks.
An STL has no colours, so the GLB is grey. Colours, pictures and parts come with OBJ, 3MF and glTF sources.
