  Tip: Optimise images

  We estimate potential to save at least 161kB* by optimising images:

  1. spitfire-595x356.png is 257kB
  2. Cold_War_11.jpg is 187kB and could be 55kB smaller
  3. research_casualty_ca... is 139kB and could be 86kB smaller
  4. Wellington_Fuselage_... is 74kB
  5. RAFStories_LOGO_squa... is 35kB and could be 20kB 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. fa-regular-400.woff2 is 174kB
  2. vendor.js?ver=1655983896 is 97kB
  3. legal.js is 91kB
  4. 571681450720036?v=2.9.62&r=sta... is 86kB
  5. gtm.js?id=GTM-K5R97T3 is 81kB
  6. fa-brands-400.woff2 is 80kB

  The page uses 2 fonts which require 254kB. Could system fonts be used instead?
