    Tip: Optimise images

    We estimate potential to save at least 20kB* by optimising images:

    1. paramedic-health-imp... is 264kB and could be 20kB smaller
    2. observatory-960.jpg is 241kB
    3. HCA960.jpg is 225kB
    4. TEF960.jpeg is 188kB
    5. lila-connect-960.jpg is 123kB
    6. parliament-960.jpg is 100kB

    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 784kB
    2. TEF960.jfif is 188kB
    3. app.js?v=nhslive is 162kB
    4. gtm.js?id=GTM-WH5D65B is 107kB

    Tip: Limit third-party code

    Here are the largest sources of third-party code:

    1. YouTube uses 1.1MB
    2. Google Tag Manager uses 202kB
    3. Optanon uses 130kB
    4. Other Google APIs/SDKs uses 64kB

    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.
