  Tip: Optimise images

  We estimate potential to save at least 3.9MB* by optimising images:

  1. Tryglyceride%20test%... is 4.2MB and could be 2.0MB smaller
  2. board-room-with-staf... is 1.6MB and could be 1.1MB smaller
  3. Breast%20cancer%20-%... is 956kB and could be 624kB smaller
  4. join-insight-communi... is 241kB and could be 157kB smaller
  5. attend-board-meeting... is 59kB and could be 16kB smaller
  6. kidney200x200.jpg is 40kB and could be 26kB 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-M55QTQ is 91kB
  2. global-nav.min.js is 83kB
  3. cookie-banner.min.js is 78kB
  4. NICE.bootstrap.min.js is 35kB
