    Tip: Optimise images

    We estimate potential to save at least 841kB* by optimising images:

    1. homepage-desktop-ban... is 1.0MB
    2. landscape-of-flowers... is 470kB and could be 349kB smaller
    3. Professor-Amanda-Gri... is 441kB
    4. 19-11-20-uon0434-cle... is 402kB
    5. iStock-1167978188.xb... is 329kB and could be 226kB smaller
    6. cleo-bryne-19-11-20-... is 324kB
    7. ammar-khazal-20-11-2... is 275kB
    8. jubilee-desktop2.xfa... is 273kB and could be 89kB smaller
    9. homepage-mobile-bann... is 272kB
    10. Landscape-of-flowers... is 159kB and could be 121kB smaller
    11. jubilee-mobile1.x6b9... is 96kB and could be 31kB smaller
    12. 100 is 26kB and could be 23kB 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. load.php?debug=false&lang=en&m... is 756kB

    Tip: Limit third-party code

    Here are the largest sources of third-party code:

    1. Kaltura Video Platform uses 976kB
    2. Google Tag Manager uses 379kB
    3. TikTok uses 155kB
    4. Cloudflare CDN uses 290kB
    5. Optanon uses 159kB
    6. Facebook uses 132kB
    7. Google Fonts uses 130kB
    8. FontAwesome CDN uses 108kB
    9. Google Analytics uses 106kB
    10. Adobe Tag Manager uses 92kB
    11. Hotjar uses 60kB
    12. JSDelivr CDN uses 51kB

    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.
