GLB to JP2: what carries over and what does not
GLB describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the JP2 afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.
