    Tip: Optimise images

    We estimate potential to save at least 821kB* by optimising images:

    1. cancer_530x354.jpg is 228kB and could be 161kB smaller
    2. mental-health_530x35... is 196kB and could be 139kB smaller
    3. primary-care_530x354... is 157kB and could be 112kB smaller
    4. ambulance_530x354.jpg is 152kB and could be 109kB smaller
    5. diabetes-promo-400.png is 137kB
    6. RightCare-how-can-we... is 134kB and could be 100kB smaller
    7. consultation-01_400x... is 97kB and could be 74kB smaller
    8. patients-02.jpg is 91kB and could be 63kB smaller
    9. hospital-corridor-40... is 83kB and could be 62kB 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.

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