    Tip: Optimise images

    We estimate potential to save at least 213kB* by optimising images:

    1. banner-20-uk.png is 989kB
    2. COP26-Web-Home-Banne... is 140kB and could be 28kB smaller
    3. coronavirus-response... is 112kB and could be 32kB smaller
    4. nav-alumni-wide2.jpg is 67kB and could be 17kB smaller
    5. world-leading.jpg is 62kB and could be 14kB smaller
    6. nav-research3-wide.jpg is 61kB and could be 43kB smaller
    7. Kings_College_campus... is 60kB and could be 13kB smaller
    8. nav-alumni-wide1.jpg is 56kB and could be 13kB smaller
    9. nav-about-2.jpg is 53kB and could be 18kB smaller
    10. Reconstruction1_web.... is 53kB and could be 9.6kB smaller
    11. Virtual-events-meeti... is 51kB and could be 9.6kB smaller
    12. Qatar_16_9_rdax_450x... is 38kB and could be 10kB smaller
    13. research_rdax_450x25... is 25kB and could be 6.3kB 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. base.js is 525kB ×6
    2. all.min.css is 174kB
    3. fa-regular-400.woff2 is 169kB

    There are 5 duplicate resources included on the page.

    The page uses 1 font which requires 169kB. Could system fonts be used instead?
