    Tip: Optimise images

    We estimate potential to save at least 1.5MB* by optimising images:

    1. EZmtf-8WoAEkJXY?form... is 579kB
    2. DSteq8QW0AQmbEe?form... is 575kB and could be 554kB smaller
    3. DSteq8QW0AQmbEe?form... is 561kB and could be 557kB smaller
    4. 1920_hackneytownhall... is 459kB and could be 353kB smaller
    5. hackney-town-hall-1.... is 246kB
    6. h-R03rOBBKl2CQZg.jpg is 225kB
    7. xvt4F4RVDV2N0yVc.jpg is 212kB
    8. LzHPtytJBs0fUeXw.jpg is 205kB
    9. Kmw9TsKHB5E1991g.jpg is 197kB
    10. 500_2.jpg?10000 is 93kB and could be 19kB smaller
    11. 500_coronation-15.jp... is 64kB and could be 12kB smaller
    12. 500_townhall1.jpg?10... is 63kB and could be 9.9kB smaller
    13. 500_img-5867.jpg?10000 is 48kB and could be 7.7kB smaller
    14. 500_hellengrogandire... is 48kB and could be 6.8kB smaller
    15. 500_pupiltakingatest... is 36kB and could be 5.8kB 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. base.js is 796kB

    Tip: Limit third-party code

    Here are the largest sources of third-party code:

    1. Twitter uses 9.3MB
    2. YouTube uses 1.0MB
    3. Facebook uses 855kB
    4. Amazon Web Services uses 810kB
    5. presspage.com uses 356kB
    6. Google Tag Manager uses 240kB
    7. Google Fonts uses 69kB
    8. Hotjar uses 68kB
    9. Other Google APIs/SDKs uses 63kB

    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.

    If you use the Twitter widget to load a timeline it may be loading as many as 100 of your recent tweets which may contain lots of images. Try setting 'data-tweet-limit' to the most recent 3.
