    Tip: Optimise images

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

    1. 207jDcF4.jpg?token=&... is 747kB and could be 444kB smaller
    2. home-people.jpg is 268kB and could be 186kB smaller
    3. home-courses.jpg is 264kB and could be 179kB smaller
    4. home-research.jpg is 257kB and could be 175kB smaller
    5. home-about-ioe.jpg is 248kB and could be 167kB smaller
    6. final_ioe_qs_2021_we... is 243kB
    7. home-clients-partner... is 203kB and could be 136kB smaller
    8. home-departments-cen... is 197kB and could be 135kB 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 (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.

    Tip: Large files

    Aside from images, here are the biggest resources:

    1. frontendcombined.js?v=7.0.005 is 201kB
    2. widget_iframe.a53eecb4584348a2... is 105kB
