Tip: Optimise images

We estimate potential to save at least 372kB* by optimising images:

WNW_community_logo_l... is 570kB and could be 364kB smaller
cost_of_living_banne... is 473kB
Sandringham_House_16... is 378kB
local_plan_examinati... is 42kB
armed_forces_403x270... is 40kB and could be 8.8kB 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:

js?id=G-7D4X979NS4 is 109kB
vendor.js?v=a3 is 88kB
react.app.js?v=325 is 67kB
fontawesome-webfont.woff2?v=4.... is 67kB
memvYaGs126MiZpBA-UvWbX2vVnXBb... is 44kB

The page uses 2 fonts which require 110kB. Could system fonts be used instead?

Tip: Limit third-party code

Here are the largest sources of third-party code:

Google Tag Manager uses 109kB
Google Fonts uses 46kB
Google CDN uses 34kB

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.
