    Tip: Optimise images

    We estimate potential to save at least 311kB* by optimising images:

    1. biochemistry.jpeg is 251kB and could be 166kB smaller
    2. students-tree-buildi... is 211kB
    3. creative-writing.x1d... is 209kB
    4. drama-st-marys-youth... is 180kB and could be 70kB smaller
    5. drama-st-marys-logo.... is 158kB
    6. guardiansofcreation.... is 107kB and could be 75kB 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
