Tip: Optimise images

We estimate potential to save at least 291kB* by optimising images:

autumn_promenade_200... is 3.8MB
Ellenborough_House_6... is 470kB
4837_400x266.jpg?t=1... is 197kB and could be 141kB smaller
4834_400x266.jpg?t=1... is 161kB and could be 120kB smaller
4_2.png is 83kB
climate_emergency_pl... is 37kB and could be 18kB smaller
letterbox.jpg is 20kB and could be 11kB 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:

cmp2ui-en.js is 118kB
Page is 114kB
m=el_main is 77kB
vendor-list-trimmed-v1.json is 70kB
fontawesome-webfont.woff2?v=4.... is 67kB

Tip: Limit third-party code

Here are the largest sources of third-party code:

InMobi uses 308kB
Other Google APIs/SDKs uses 110kB
Google CDN uses 47kB
Google Fonts uses 36kB

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.
