    Tip: Optimise images

    We estimate potential to save at least 24kB* by optimising images:

    1. bank-frontage.jpg is 269kB
    2. bg-1.png is 107kB
    3. notes-fan.jpg?h=316&... is 95kB and could be 19kB smaller
    4. exchanging-banknotes... is 46kB and could be 5.5kB 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 (JPG image) or (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. boe.vendor.min.js?v=1 is 66kB
    2. 9R3WH-S6EDC-8JGQW-55286-CGTTF is 52kB
    3. blsw-rg.woff2 is 37kB
    4. blsw-lt.woff2 is 37kB
    5. blsw-bd.woff2 is 37kB

    The page uses 3 fonts which require 111kB. Could system fonts be used instead?
