  Tip: Optimise images

  We estimate potential to save at least 1.2MB* by optimising images:

  1. New-kings.jpg is 1.7MB and could be 370kB smaller
  2. Web-Banner-2400x1020... is 1.3MB and could be 242kB smaller
  3. G02_Headshot_Ana.jpg is 723kB and could be 128kB smaller
  4. Jan-Starts-2400x1020... is 569kB and could be 107kB smaller
  5. Recruitment2.jpg is 244kB and could be 47kB smaller
  6. trilemma-mod.jpg is 218kB and could be 48kB smaller
  7. Stats-background.jpg is 90kB and could be 82kB smaller
  8. library-exterior.jpg is 81kB and could be 18kB smaller
  9. hemp_seeds.jpg is 80kB and could be 18kB smaller
  10. nav-alumni-wide2.jpg is 67kB and could be 17kB smaller
  11. nav-research3-wide.jpg is 61kB and could be 43kB smaller
  12. nav-alumni-wide1.jpg is 56kB and could be 13kB smaller
  13. nav-about-2.jpg is 53kB and could be 18kB smaller
  14. Kings.jpg is 51kB and could be 9.8kB 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. abdn-design-system-site.css?v=... is 1.2MB
  2. fa-regular-400.woff2 is 389kB
  3. fa-solid-900.woff2 is 329kB
  4. fa-brands-400.woff2 is 106kB

  The page uses 3 fonts which require 825kB. Could system fonts be used instead?

  Tip: Limit third-party code

  Here are the largest sources of third-party code:

  1. Civic uses 96kB
  2. Adobe TypeKit uses 68kB
  3. Google Fonts uses 49kB
  4. jQuery CDN uses 31kB

  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.
