  Tip: Optimise images

  We estimate potential to save at least 801kB* by optimising images:

  1. 1608759-1200-x-322.a... is 340kB and could be 212kB smaller
  2. pg-event-diamond-ban... is 263kB and could be 209kB smaller
  3. grads18diamond.ashx is 169kB and could be 114kB smaller
  4. homepage_banner_2000... is 125kB and could be 71kB smaller
  5. diamond-1-lab-studen... is 108kB and could be 72kB smaller
  6. diamond-4-nursing-st... is 107kB and could be 74kB smaller
  7. 13525_400x400.ashx?h... is 94kB and could be 21kB smaller
  8. image-5v3.ashx?h=960... is 80kB and could be 5.8kB smaller
  9. diamond-5-student.as... is 48kB and could be 9.8kB smaller
  10. small-Logo.jpg is 17kB and could be 12kB 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. gtm.js?id=GTM-PL6QT8 is 106kB
  2. 11.cache.js is 93kB
  3. internationalcollege_homepage_... is 89kB

  Tip: Limit third-party code

  Here are the largest sources of third-party code:

  1. TrustArc uses 317kB
  2. Google Tag Manager uses 106kB
  3. YouTube uses 72kB
  4. Google Fonts uses 40kB

  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.
