    Tip: Optimise images

    We estimate potential to save at least 1.0MB* by optimising images:

    1. s465_Eccles.jpg is 253kB and could be 181kB smaller
    2. s465_Sheffield.jpg is 191kB and could be 126kB smaller
    3. s465_CI_portrait_2.jpg is 177kB and could be 138kB smaller
    4. s465_Rowlands_Castle... is 173kB and could be 113kB smaller
    5. s465_Twickenham.jpg is 168kB and could be 116kB smaller
    6. s465_Grosmont.jpg is 168kB and could be 111kB smaller
    7. GOVUKlogo.jpg is 150kB and could be 108kB smaller
    8. s465_Audenshaw.jpg is 141kB and could be 104kB 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.
