  Tip: Optimise images

  We estimate potential to save at least 788kB* by optimising images:

  1. AdobeStock_108590743... is 568kB and could be 36kB smaller
  2. homepage-banner-min-... is 559kB
  3. menu-advert-2.jpg is 496kB and could be 304kB smaller
  4. campus-5-min.jpg is 454kB
  5. online-business-meet... is 453kB and could be 98kB smaller
  6. 2-Students-in-the-St... is 424kB and could be 108kB smaller
  7. campus-4-min.jpg is 417kB
  8. wrexham-university-n... is 226kB and could be 72kB smaller
  9. DSCF9405_800.jpg is 222kB and could be 80kB smaller
  10. DSC_4370.jpg is 185kB and could be 22kB smaller
  11. DSCF7384_800.jpg is 175kB and could be 67kB 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. app-1.css is 291kB

  Tip: Limit third-party code

  Here are the largest sources of third-party code:

  1. Other Google APIs/SDKs uses 129kB
  2. TikTok uses 151kB
  3. Google Tag Manager uses 191kB
  4. ally.ac uses 126kB
  5. Facebook uses 95kB
  6. Google Fonts uses 88kB
  7. Adobe TypeKit uses 86kB
  8. Cludo uses 54kB
  9. Crazy Egg uses 38kB
  10. JSDelivr CDN uses 35kB

  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.
