No. STL stores only geometry, so any colors, materials and textures in the GLB are dropped. That is a limitation of the STL format itself, not the converter.
The converter exports a binary STL containing your model geometry, which is exactly what slicers expect. As with any model, open it in your slicer to check it before printing.
The converter exports binary STL, which is significantly smaller and faster to load than ASCII STL.
No. The converter runs entirely in your browser, so there is nothing to download or install.
