    Tip: Optimise images

    We estimate potential to save at least 4.1kB* by optimising images:

    1. Francis-Close-Hall.jpg is 387kB
    2. Oxstalls-Gloucester-... is 225kB
    3. student-life-2023-12... is 151kB
    4. international-2023-1... is 146kB
    5. boxer-1024x1024.jpg is 131kB and could be 4.1kB smaller
    6. tef-logo-white.png is 80kB

    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.

    Tip: Large files

    Aside from images, here are the biggest resources:

    1. clearing-hero-2023.mp4 is 1.6MB
    2. confetti.mp4 is 871kB
    3. gtm.js?id=GTM-T95XP57 is 113kB
    4. swiper.min.js?ver=1.1 is 44kB

    Tip: Limit third-party code

    Here are the largest sources of third-party code:

    1. Google Tag Manager uses 113kB
    2. Unpkg uses 40kB

    Third-party code can significantly impact load performance. Limit the number of redundant third-party providers and try to load third-party code after your page has primarily finished loading.
