We estimate potential to save at least 134kB* by optimising images:
First, check that images are appropriately sized - you most likely don't need a 6000x4000 pixel image straight from a digital camera. In Windows, the Photos software will let you quickly shrink huge images and will give you an improvement.
*This is an estimate from Google PageSpeed and you may get much better results than this in practice.
