Tip: Optimise images

We estimate potential to save at least 75kB* by optimising images:

sweet-gum-liquidamba... is 169kB
polling_station_sign... is 149kB
stay-connected.jpg is 82kB and could be 57kB smaller
southampton-launches... is 60kB
pensions-benefit-hom... is 34kB
col-homepage-footer-... is 31kB and could be 18kB 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:

The page uses 1 font which requires 110kB. Could system fonts be used instead?

Tip: Limit third-party code

Here are the largest sources of third-party code:

Civic uses 96kB
Google Tag Manager uses 101kB
Cloudflare CDN uses 130kB
jQuery CDN uses 99kB
Bootstrap CDN uses 49kB

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.
