  Tip: Optimise images

  We estimate potential to save at least 433kB* by optimising images:

  1. middle_bar8.png is 1.2MB
  2. homepage_sep23.jpg is 635kB and could be 407kB smaller
  3. menu_back_mission.png is 235kB
  4. top_back_glt3.png is 233kB
  5. menu_back_student.png is 207kB
  6. menu_back_education.... is 201kB
  7. menu_back_la.png is 182kB
  8. footer_back.png is 82kB
  9. inthepicture_back2.png is 81kB
  10. fblogo.jpg is 14kB and could be 13kB smaller
  11. twitterlogo.jpg is 14kB and could be 13kB 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. Google Tag Manager uses 152kB
  2. Facebook uses 94kB

  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.
