# How does image optimization affect crawling, rendering and user experience?

> Images affect:

- bandwidth;

- loading performance;

- LCP;

- visual stability;

- accessibility;

- image search.

Use appropriate dimensions, modern formats where supported, responsive images and explicit dimensions.

Do not sacrifice meaningful image quality solely to achieve a performance metric.
