  Tip: Optimise images

  We estimate potential to save at least 1.7MB* by optimising images:

  1. namouflage--primary-... is 937kB and could be 724kB smaller
  2. social-conversation-... is 830kB and could be 15kB smaller
  3. namouflage--dark-blu... is 736kB and could be 503kB smaller
  4. footsteps-forces_tea... is 574kB and could be 375kB smaller
  5. namouflage--jagged--... is 507kB
  6. foe-friend-notitle-e... is 401kB
  7. lynx-atrium_slice.jp... is 341kB
  8. 240496_teaser.jpg is 339kB and could be 56kB smaller
  9. 292574_slice_v2.jpg?... is 322kB
  10. 184453_teaser.jpg is 301kB and could be 53kB 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.
