    Tip: Optimise images

    We estimate potential to save at least 1.4MB* by optimising images:

    1. enu_homepage_banner_... is 466kB and could be 297kB smaller
    2. coronavirusdiamond.jpg is 355kB and could be 276kB smaller
    3. 1608759-1200-x-322.jpg is 340kB and could be 212kB smaller
    4. grads2021.jpg is 279kB and could be 172kB smaller
    5. specialsdiamond2021.... is 239kB and could be 135kB smaller
    6. katediamond.jpg is 199kB and could be 129kB smaller
    7. diamond-1-lab-studen... is 120kB and could be 83kB smaller
    8. diamond-4-nursing-st... is 119kB and could be 85kB smaller
    9. 13525_400x400.jpg?h=... is 94kB and could be 21kB smaller
    10. image-5v3.jpg?h=960&... is 80kB and could be 5.8kB smaller
    11. small-Logo.jpg is 17kB and could be 12kB smaller

    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 tinyjpg.com (JPG image) or tinypng.com (PNG image) to further optimise your image. This will strip out metadata that may be taking up lots of space.
