    Tip: Optimise images

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

    1. cop28,urban.jpg is 82kB
    2. IMG_4682web.jpg is 74kB and could be 9.8kB smaller
    3. 65412bb7275f3.jpg is 52kB and could be 6.8kB smaller
    4. QS-Sustainability-Ra... is 43kB and could be 8.8kB 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. gtm.js?id=GTM-P4FCNF is 123kB
    2. main.MTdjYzNiZDU2MQ.js is 111kB
    3. jquery.mmenu.all.js is 102kB
    4. js?id=G-D5RC5GKKXW&l=dataLayer... is 92kB
    5. jquery-3.6.0.min.js is 90kB
    6. jquery-ui.min.js is 69kB
    7. master-2.css is 59kB
    8. fbevents.js is 56kB

    Tip: Limit third-party code

    Here are the largest sources of third-party code:

    1. Google Tag Manager uses 215kB
    2. TikTok uses 151kB
    3. Adobe TypeKit uses 293kB
    4. Facebook uses 170kB
    5. Google CDN uses 69kB

    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.
