Tip: Optimise images

We estimate potential to save at least 241kB* by optimising images:

Millennium_Square.jpg is 729kB and could be 90kB smaller
Polling_station_2.jpg is 263kB and could be 48kB smaller
Coventry_at_night.jpg is 183kB and could be 47kB smaller
Brown_lidded_bin_1.jpg is 105kB and could be 27kB smaller
Coventry_skyline_wit... is 100kB and could be 29kB 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:

Tip: Limit third-party code

Here are the largest sources of third-party code:

Azure Web Services uses 3.1MB
botframework.com uses 892kB
Civic uses 96kB
Browsealoud uses 289kB
FontAwesome CDN uses 134kB
Google Fonts uses 46kB
Unpkg uses 46kB
Google CDN uses 31kB

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.
