    Tip: Optimise images

    We estimate potential to save at least 858kB* by optimising images:

    1. large.png is 1.5MB
    2. Depositphotos_524592... is 1.0MB and could be 741kB smaller
    3. September.jpg is 385kB
    4. small.png is 271kB
    5. 15OpenDay_Croydon22-... is 240kB and could be 50kB smaller
    6. smiling-students-ris... is 221kB and could be 32kB smaller
    7. small.png is 207kB
    8. engineering-test-ban... is 202kB and could be 29kB smaller
    9. Hub-students-on-the-... is 196kB
    10. Southwark-Campus.jpg is 187kB and could be 5.7kB 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. vendor.js?h=231d00f is 653kB

    Tip: Limit third-party code

    Here are the largest sources of third-party code:

    1. Cookiebot uses 132kB
    2. FontAwesome CDN uses 163kB
    3. jQuery CDN uses 135kB
    4. Cloudflare CDN uses 107kB

    Third-party code can significantly impact load performance. Limit the number of redundant third-party providers and try to load third-party code after your page has primarily finished loading.
