  Tip: Optimise images

  We estimate potential to save at least 10.0kB* by optimising images:

  1. screenshot-2022-06-0... is 419kB
  2. home_who-we-are_prom... is 115kB
  3. home_what-we-do_prom... is 112kB
  4. eis_home_hero_resize... is 108kB
  5. home_support-service... is 95kB
  6. eis-20th-anniversary... is 91kB
  7. eis-insider-performa... is 42kB and could be 10.0kB 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. main.js is 292kB
  2. recaptcha__en.js is 147kB
  3. otBannerSdk.js is 77kB
  4. main.css is 44kB
