  Tip: Optimise images

  We estimate potential to save at least 233kB* by optimising images:

  1. winter-homepage-bann... is 698kB and could be 164kB smaller
  2. swimmer-underwater-n... is 157kB
  3. fishing-at-sunset-sl... is 133kB
  4. img_8.pngimg_8.png is 112kB
  5. img_11.pngimg_11.png is 112kB
  6. img_5.pngimg_5.png is 112kB
  7. img_1.pngimg_1.png is 109kB
  8. img_9.pngimg_9.png is 108kB
  9. img_12.pngimg_12.png is 108kB
  10. img_6.pngimg_6.png is 106kB
  11. (USE-THIS-ONE)-UoS-G... is 65kB and could be 27kB smaller
  12. 450x338-thumbnail-im... is 65kB and could be 27kB smaller
  13. Footballers-450x338.... is 53kB and could be 15kB 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: Limit third-party code

  Here are the largest sources of third-party code:

  1. thirdlight.com uses 1.3MB
  2. Google Tag Manager uses 106kB
  3. Civic uses 97kB

  Third-party code can significantly impact load performance. Limit the number of redundant third-party providers and try to load third-party code after your page has primarily finished loading.
