  Tip: Optimise images

  We estimate potential to save at least 988kB* by optimising images:

  1. s465_Lady_Howard_FPC... is 244kB and could be 164kB smaller
  2. s465_Surbiton2.jpg is 237kB and could be 159kB smaller
  3. s465_Belle_Isle_jn.JPG is 196kB and could be 131kB smaller
  4. s465_Farnborough_Nor... is 188kB and could be 123kB smaller
  5. s465_AR2021-hi-viz.jpg is 161kB and could be 114kB smaller
  6. s465_Uphill_Jn.jpg is 150kB and could be 106kB smaller
  7. GOVUKlogo.jpg is 150kB and could be 108kB smaller
  8. s465_Andrew_Hall-GOV... is 113kB and could be 81kB 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.
