    Tip: Optimise images

    We estimate potential to save at least 96kB* by optimising images:

    1. Matti-850-x-510.png is 717kB
    2. Charlotte-Manser-Hea... is 697kB
    3. Fion-header2.jpg is 145kB and could be 51kB smaller
    4. jana-header.jpg is 98kB and could be 22kB smaller
    5. mike-header.jpg is 89kB and could be 24kB 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. base.js is 786kB ×2
    2. base.js is 784kB ×6

    There are 6 duplicate resources included on the page.

    Tip: Limit third-party code

    Here are the largest sources of third-party code:

    1. YouTube uses 8.0MB
    2. Google Tag Manager uses 211kB
    3. Cookiebot uses 125kB
    4. TikTok uses 263kB
    5. Other Google APIs/SDKs uses 623kB
    6. Google Fonts uses 230kB
    7. Facebook uses 132kB
    8. Adform uses 35kB

    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.
