Potential savings of 151 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity. Learn how to reduce unused JavaScript.
Efficiently encode images
Potential savings of 172 KiB
Optimized images load faster and consume less cellular data. Learn how to efficiently encode images.
Avoid multiple page redirects
Potential savings of 630 ms
Redirects introduce additional delays before the page can be loaded. Learn how to avoid page redirects.
