Tip: Optimise images

We estimate potential to save at least 1.6MB* by optimising images:

banner-cym-645x265px... is 743kB and could be 679kB smaller
empty-property-banne... is 411kB
road-safety-wales-st... is 357kB
nature-emergency-wel... is 344kB and could be 218kB smaller
minnie-pallister-web... is 212kB and could be 126kB smaller
bluetongue-welsh.jpg... is 188kB and could be 109kB smaller
straying-sheep-welsh... is 184kB and could be 104kB smaller
welsh-school-of-the-... is 168kB and could be 101kB smaller
electric-vehicle-cha... is 130kB and could be 77kB smaller
ufsm-banner-cym.jpg?... is 129kB and could be 75kB smaller
col-banner-cym.png?w... is 100kB and could be 62kB 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:

all.min.js is 759kB
fa-solid-900.woff2 is 156kB

The page uses 1 font which requires 156kB. 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 108kB

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.
