    Tip: Optimise images

    We estimate potential to save at least 25kB* by optimising images:

    1. nicole.png is 339kB
    2. earth-1149733_1920.jpg is 308kB
    3. TEF-gold-gold-gold-9... is 137kB
    4. global-map-thumb-2.jpg is 132kB
    5. global-map-thumb-4.jpg is 113kB
    6. global-map-thumb-1.jpg is 106kB
    7. 16357-1400x600.jpg is 102kB
    8. cop28-nav-image.jpg is 67kB and could be 25kB 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. base.js is 784kB ×2
    2. gtm.js?id=GTM-K4NS9FB is 109kB

    There is 1 duplicate resource included on the page.

    Tip: Limit third-party code

    Here are the largest sources of third-party code:

    1. YouTube uses 2.1MB
    2. Google Tag Manager uses 198kB
    3. FontAwesome CDN uses 156kB
    4. Facebook uses 134kB
    5. AB Tasty uses 90kB
    6. Google Fonts uses 81kB
    7. Other Google APIs/SDKs uses 66kB
    8. jQuery CDN uses 34kB

    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.
