  Tip: Optimise images

  We estimate potential to save at least 925kB* by optimising images:

  1. s465_01462_N26_govuk... is 270kB and could be 190kB smaller
  2. s465_HS2_200114_Birm... is 257kB and could be 178kB smaller
  3. s465_HS2_181121_Curz... is 208kB and could be 143kB smaller
  4. s465_HS2_200114_Birm... is 201kB and could be 140kB smaller
  5. s465_Pendigo_lake_96... is 181kB and could be 131kB smaller
  6. s465_CEO__resized_.jpg is 152kB and could be 114kB smaller
  7. s465_Crowders_visit_... is 71kB
  8. gov_uk_logo.jpg is 31kB 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.
