    Tip: Optimise images

    We estimate potential to save at least 58kB* by optimising images:

    1. cop-26.jpg is 199kB and could be 37kB smaller
    2. north-laine.jpg is 171kB
    3. mandela-hall.jpg is 167kB
    4. good-university-guid... is 144kB and could be 21kB smaller
    5. spotlight-2.jpg is 134kB
    6. campus-wide-faded.jpg is 129kB
    7. homepage.jpg?v3 is 127kB
    8. footer-xx-large.jpg is 78kB

    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.

    Next you could try using (JPG image) or (PNG image) to further optimise your image. This will strip out metadata that may be taking up lots of space.

    *This is an estimate from Google PageSpeed and you may get much better results than this in practice.
