    Tip: Optimise images

    We estimate potential to save at least 179kB* by optimising images:

    1. library.png is 515kB
    2. lights1-2024.jpg is 355kB
    3. irongate.jpg is 235kB and could be 145kB smaller
    4. DickWhit25-newsroom.... is 86kB
    5. foster-parent-and-ch... is 63kB and could be 17kB smaller
    6. e-billing.jpg is 27kB and could be 8.3kB smaller
    7. art-competition.jpg is 22kB and could be 9.2kB 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. app-6a4d46eb.js is 1.5MB
    2. index.js is 375kB
    3. home.css is 144kB
    4. mc-validate.js is 143kB
    5. js?id=G-G9H7HD8WSH is 137kB
    6. 135.d8a85b43a32c051e694e.js is 89kB

    Tip: Limit third-party code

    Here are the largest sources of third-party code:

    1. Google Tag Manager uses 137kB
    2. Browsealoud uses 292kB
    3. Amazon Web Services uses 143kB
    4. Google Fonts uses 47kB

    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.
