  Tip: Optimise images

  We estimate potential to save at least 542kB* by optimising images:

  1. cancer_530x354.jpg is 228kB and could be 161kB smaller
  2. primary-care_530x354... is 157kB and could be 112kB smaller
  3. ambulance_530x354.jpg is 152kB and could be 109kB smaller
  4. website-home-montage... is 129kB and could be 51kB smaller
  5. delivery-plan-electi... is 106kB and could be 33kB smaller
  6. patients-02.jpg is 91kB and could be 63kB smaller
  7. mental-health.jpg is 61kB 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. main-630962c4ef3c5d62ff5be8347... is 88kB
  2. jquery.min.js?ver=6.0 is 34kB
  3. langs.min.js?ver=6.0 is 32kB
