  Tip: Optimise images

  We estimate potential to save at least 5.3kB* by optimising images:

  1. itchen_bridge.jpg is 227kB
  2. green-flag-sign.jpg is 129kB
  3. civic-centre-drone-s... is 96kB and could be 5.3kB smaller
  4. councillor-winning-h... is 43kB
  5. southampton-2035-pla... is 36kB
  6. civic-centre-home.jpg is 36kB

  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. gtm.js?id=GTM-NJPR6XX is 128kB
  2. fa-brands-400.woff2 is 110kB
  3. cookieControl-9.x.min.js is 97kB
  4. jquery-ui.min.js is 68kB

  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:

  1. Civic uses 98kB
  2. Google Tag Manager uses 128kB
  3. Cloudflare CDN uses 130kB
  4. jQuery CDN uses 99kB
  5. Bootstrap CDN uses 43kB

  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.
