  Tip: Optimise images

  1. Postgraduate_Banner_... is 205kB
  2. warwick-university-r... is 122kB
  3. undergraduate-open-d... is 121kB

  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. fa-light-300.woff2.149420877782 is 184kB
  2. fa-duotone-900.woff2.211389069... is 182kB
  3. fa-regular-400.woff2.125978268... is 169kB
  4. fa-solid-900.woff2.254471731011 is 137kB
  5. id7-bundle-render.js.256487382... is 131kB
  6. gtm.js?id=GTM-55N43RF is 111kB
  7. pack7.css.260878342122 is 101kB

  Tip: Limit third-party code

  Here are the largest sources of third-party code:

  1. cloudfront.net uses 1.0MB
  2. Google Tag Manager uses 111kB
  3. Google Fonts uses 46kB

  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.
