    Tip: Optimise images

    We estimate potential to save at least 22kB* by optimising images:

    1. Media,1083278,smxx.jpg is 369kB
    2. Media,1518648,smxx.jpg is 230kB
    3. Media,2140329,smxx.jpg is 181kB and could be 22kB smaller
    4. Media,1000376,smxx.jpg is 153kB
    5. Media,1301203,smxx.jpg is 147kB

    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. fa-regular-400.woff2 is 396kB
    2. fa-solid-900.woff2 is 328kB
    3. fa-brands-400.woff2 is 111kB
    4. Media,1004614,smxx.js?v=1.0 is 102kB
    5. cookieControl-9.x.min.js is 95kB

    The page uses 3 fonts which require 836kB. Could system fonts be used instead?

    Tip: Limit third-party code

    Here are the largest sources of third-party code:

    1. Civic uses 96kB
    2. Google Tag Manager uses 52kB

    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.
