    Tip: Optimise images

    We estimate potential to save at least 4.6MB* by optimising images:

    1. Accommodation-3.jpg is 5.7MB and could be 2.5MB smaller
    2. Canalside.jpg is 1.4MB and could be 767kB smaller
    3. Ama-and-Deanna.PNG is 1.1MB
    4. Discover-banner-imag... is 665kB and could be 412kB smaller
    5. Whitehall-3.jpg is 661kB and could be 439kB smaller
    6. Student-life.jpg is 364kB and could be 165kB smaller
    7. Blue-pills.-Credit_-... is 271kB and could be 220kB smaller
    8. nelarine-cornelius-6... is 128kB and could be 35kB smaller
    9. Tim-Bale.JPG is 33kB and could be 26kB smaller
    10. QMUL-gradient-05-hor... is 26kB and could be 11kB 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.

    Tip: Large files

    Aside from images, here are the biggest resources:

    1. 433550753908211?v=2.9.48&r=sta... is 90kB
