    Tip: Optimise images

    We estimate potential to save at least 18kB* by optimising images:

    1. 829205ba-97de-46fa-a... is 791kB
    2. Homepage-Loop-2023-2... is 292kB and could be 18kB 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. cd06bb98-1d09-4a9e-b2c4-b04200... is 8.3MB
    2. quiz.umd.js is 4.4MB
    3. commons.js is 1.2MB
    4. react-components.umd.js is 954kB
    5. Core.js is 720kB
    6. vendors.js is 619kB
    7. viewer.umd.js is 570kB
    8. ScriptResource.axd?d=1gvto_Fuk... is 533kB
    9. hls.min.js is 322kB

    Tip: Limit third-party code

    Here are the largest sources of third-party code:

    1. panopto.eu uses 10.5MB
    2. Google Tag Manager uses 203kB
    3. TikTok uses 149kB
    4. cloudfront.net uses 9.1MB
    5. terminalfour.net uses 506kB
    6. Optanon uses 327kB
    7. Cloudflare CDN uses 85kB
    8. Hotjar uses 68kB
    9. Google Fonts uses 37kB
    10. jQuery CDN uses 31kB

    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.
