    Tip: Optimise images

    We estimate potential to save at least 265kB* by optimising images:

    1. liter-of-light-banne... is 602kB and could be 82kB smaller
    2. chemistry-750x500.jpg is 295kB and could be 183kB smaller
    3. study-at-st-andrews-... is 63kB
    4. alumni-750x500.jpg is 49kB

    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. screen.css is 150kB
    2. core.min.js is 91kB
    3. cookieControl-9.x.min.js is 78kB
    4. fa-solid-900.woff2 is 75kB
    5. fa-brands-400.woff2 is 72kB
    6. gtm.js?id=GTM-KW2XNGZ is 55kB

    The page uses 2 fonts which require 146kB. Could system fonts be used instead?
