Optimized image

Performance

An optimized image has the right weight, format, size and loading behavior. It is not only about looking good, but about not breaking speed or page stability.

Optimized image
It matters because images are often among the heaviest resources on a website. A bad image can slow everything down and make the layout jump while loading.
  • Measure loading, stability and interaction under real conditions.
  • Optimize heavy resources before adding new visual layers.
  • Reserve space for images and elements that load later.
  • Review mobile impact, not only desktop.
