  Tip: Optimise images

  We estimate potential to save at least 195kB* by optimising images:

  1. image-700x318.png is 82kB
  2. ezgif.com-gif-maker-... is 80kB
  3. food-commissionBig.jpg is 77kB and could be 51kB smaller
  4. carlisle131-2100x140... is 63kB
  5. lake-district-nation... is 62kB and could be 39kB smaller
  6. ezgif.com-gif-maker.... is 62kB
  7. BAE_systems_logo.jpg is 48kB and could be 38kB smaller
  8. Sellafield-Logo.jpg is 48kB and could be 37kB smaller
  9. Pfizer_logo.jpg is 44kB and could be 32kB 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. UoC-Home-Page-Video-(Text-Cent... is 4.7MB
  2. gtm.js?id=GTM-PGGZPB is 110kB
  3. js?id=G-F17233815R&l=dataLayer... is 93kB
  4. connect.js is 85kB

  Tip: Limit third-party code

  Here are the largest sources of third-party code:

  1. Google Tag Manager uses 203kB
  2. Facebook uses 168kB
  3. commbox.io uses 92kB
  4. userway.org uses 62kB
  5. Unbounce uses 51kB

  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.
