    Tip: Optimise images

    We estimate potential to save at least 129kB* by optimising images:

    1. our-mission-bg.png is 1.2MB
    2. homepage-map-image.png is 314kB
    3. current-threats-bg.jpg is 96kB and could be 65kB smaller
    4. our-history-bg.jpg is 75kB and could be 45kB smaller
    5. british-intel-explai... is 30kB and could be 19kB 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. video.js is 151kB
    2. SourceSansPro-Regular.otf is 134kB
    3. otBannerSdk.js is 87kB
    4. gtm.js?id=GTM-MC7593M is 52kB
    5. BebasNeueRegular.otf is 46kB
    6. BebasNeueBook.otf is 46kB

    The page uses 3 fonts which require 227kB. Could system fonts be used instead? There are 3 TTF/OTF fonts on the page - WOFF2 versions of these fonts may be smaller.
