  Tip: Optimise images

  We estimate potential to save at least 69kB* by optimising images:

  1. wonderlab-national-s... is 144kB
  2. journal-september-20... is 79kB and could be 47kB smaller
  3. ee3blog-512x384.jpg is 57kB and could be 22kB 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. SMGSans-Light.woff is 90kB
  2. SMGSans-Regular.woff is 88kB
  3. SMGSans-Bold.woff is 86kB
  4. otBannerSdk.js is 76kB
  5. gtm.js?id=GTM-P59SKD is 62kB
  6. www-widgetapi.js is 53kB
  7. components.js?ver=5.9.3 is 50kB

  The page uses 3 fonts which require 263kB. Could system fonts be used instead?
