  CO2 estimatePage size

  Note: from 1st November 2022 we adopted version 3 of the methodology for estimating CO2 emissions. This will tend to lower CO2 estimates for a given size.

  Tip: Optimise images

  We estimate potential to save at least 267kB* by optimising images:

  1. desktopPanelImage.pn... is 2.0MB
  2. original.png?m=17410... is 1.8MB
  3. original.png?m=17397... is 1.8MB
  4. original.png?m=17231... is 1.2MB
  5. original.jpg?m=17404... is 387kB and could be 267kB smaller
  6. imageBannerBackgroun... is 163kB

  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. dynamic.js?v=638765847218870000 is 286kB
  2. js?id=G-Q9K2LT8GZN is 120kB
  3. dynamic.css?v=638765879060730000 is 108kB
  4. gtm.js?id=GTM-MGPJFH6 is 104kB

  Tip: Limit third-party code

  Here are the largest sources of third-party code:

  1. Clarity uses 33kB
  2. Google Tag Manager uses 225kB
  3. Google Fonts uses 39kB

  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.
