  Tip: Optimise images

  We estimate potential to save at least 1.9MB* by optimising images:

  1. university-of-readin... is 976kB and could be 629kB smaller
  2. phd-studentships-ban... is 667kB and could be 458kB smaller
  3. mvod-mobile.jpg is 253kB and could be 154kB smaller
  4. mvod-desktop.jpg is 253kB and could be 154kB smaller
  5. disability-history-m... is 162kB and could be 110kB smaller
  6. partnering-for-plane... is 159kB
  7. disability-history-m... is 147kB and could be 102kB smaller
  8. connectedworld296x15... is 94kB and could be 69kB smaller
  9. assets-home-Great-co... is 77kB and could be 56kB smaller
  10. assets-home-Explore-... is 55kB and could be 32kB smaller
  11. assets-home-Get-a-Ro... is 49kB and could be 29kB smaller
  12. teaching-and-learnin... is 43kB and could be 23kB smaller
  13. assets-home-latest-n... is 41kB and could be 26kB smaller
  14. business-296x150px.jpg is 41kB and could be 20kB smaller
  15. unibuddy256x150.jpg is 26kB and could be 14kB 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. assets-css-main.css is 199kB
  2. web-library.min.js is 180kB
  3. gtm.js?id=GTM-TC325M is 118kB

  Tip: Limit third-party code

  Here are the largest sources of third-party code:

  1. Google Tag Manager uses 211kB
  2. TikTok uses 151kB
  3. Facebook uses 172kB
  4. Hotjar uses 60kB

  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.
