  Tip: Optimise images

  We estimate potential to save at least 1.6MB* by optimising images:

  1. 22-0121-sustainable-... is 748kB and could be 476kB smaller
  2. Dementia-stride-stor... is 511kB
  3. 23-0596-RFTW-COMPOSI... is 407kB and could be 258kB smaller
  4. Welcome-Sept23-DSC11... is 389kB and could be 254kB smaller
  5. Can-we-chnage-the-wo... is 314kB and could be 199kB smaller
  6. Study-at-LSE-DSC3136... is 281kB and could be 190kB smaller
  7. 23-0035-747X420.jpg is 169kB and could be 100kB smaller
  8. High-seas-May23-747x... is 160kB and could be 88kB smaller
  9. Student-Hub-747x420.... is 69kB and could be 17kB smaller
  10. school-child-747-x-4... is 58kB and could be 13kB 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-NPVJBJ is 121kB
  2. main.MTdjYzNiZDU2MQ.js is 113kB

  Tip: Limit third-party code

  Here are the largest sources of third-party code:

  1. Google Tag Manager uses 212kB
  2. TikTok uses 153kB
  3. Facebook uses 209kB
  4. Google Analytics uses 92kB
  5. Google Fonts uses 39kB

  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.
