Tip: Optimise images

We estimate potential to save at least 311kB* by optimising images:

Homecare_Recruitment... is 241kB and could be 121kB smaller
Litter_Lotto_-_Web_B... is 217kB
jigsaw.jpg is 160kB and could be 99kB smaller
LEZ-Web-banner-V1-2.... is 51kB
SG-Banner---Web-v2_(... is 47kB and could be 27kB smaller
GlasgowMark2021_20mm... is 40kB and could be 35kB smaller
betterconnectedplus-... is 23kB and could be 18kB smaller
twitter.jpg is 12kB and could be 12kB 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-1M8G5BKKHG is 101kB
jquery-1.8.2.min.js is 34kB

Tip: Limit third-party code

Here are the largest sources of third-party code:

Google Tag Manager uses 101kB

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.
