  Tip: Optimise images

  We estimate potential to save at least 522kB* by optimising images:

  1. s465_CIRCE_concept_c... is 224kB
  2. s465_Dr_Paul_Hollins... is 193kB
  3. s465_AI_Fest_Graphic... is 171kB
  4. s712_VCDS_Awards.jpg is 160kB and could be 46kB smaller
  5. s465_F-35_Graphic_of... is 153kB
  6. s465_Matt_Chinn_960x... is 119kB and could be 94kB smaller
  7. s465_Andy_Bell_gov_u... is 110kB and could be 83kB 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.
