    Tip: Optimise images

    We estimate potential to save at least 256kB* by optimising images:

    1. Media,1207867,smxx-6... is 368kB
    2. Media,1214502,smxx.jpg is 268kB and could be 196kB smaller
    3. Media,1022671,smxx.jpg is 255kB and could be 35kB smaller
    4. Media,1219631,smxx.jpg is 236kB
    5. Media,980995,smxx.jpg is 156kB and could be 26kB smaller
    6. Media,1000376,smxx.jpg is 153kB
    7. Media,1219630,smxx.jpg is 120kB

    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. fa-regular-400.woff2 is 110kB
    2. Media,1004614,smxx.js is 102kB
    3. Media,1154080,smxx.js is 78kB

    The page uses 1 font which requires 110kB. Could system fonts be used instead?
