    Tip: Optimise images

    We estimate potential to save at least 162kB* by optimising images:

    1. students-walking-out... is 2.3MB
    2. snake-770.png is 466kB
    3. cop28-banner.jpg is 454kB
    4. cop28-banner.jpg?cx=... is 290kB
    5. cop28-uol-contributi... is 276kB and could be 63kB smaller
    6. hero-banners-mccann3... is 239kB
    7. artist_s_impression_... is 224kB and could be 36kB smaller
    8. hazel-tree-990.jpg is 107kB
    9. fcltcwcx0ai4wm0.jpg?... is 80kB and could be 34kB smaller
    10. uncertainty-770.jpg is 66kB and could be 19kB smaller
    11. winter-wonderland-40... is 29kB and could be 9.6kB 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.

    Tip: Large files

    Aside from images, here are the biggest resources:

    1. manish-pareek-770.gif is 282kB
    2. gtm.js?id=GTM-ND9NQP is 131kB

    Tip: Limit third-party code

    Here are the largest sources of third-party code:

    1. Civic uses 96kB
    2. Google Tag Manager uses 131kB
    3. Flockler uses 87kB
    4. YouTube uses 72kB

    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.
