Image Optimization

Image optimization means preparing and delivering images so they look appropriate while using reasonable bandwidth and loading efficiently. The work can include choosing a modern format, generating multiple dimensions, setting correct display sizes, compressing files, and deciding which images should load first. A cleaning service's gallery may need detailed photos, but sending oversized originals to every phone can slow the page unnecessarily. Image compression is one part of this broader process; it specifically reduces file size. Optimization also requires visual review, because an aggressively compressed photograph may conceal useful details of the work being shown. Descriptive alternative text addresses a separate accessibility need.
