2 practical guides to help you understand the details and choose your next step.
Where to begin
A smaller file is only one part of a useful website image. Correct dimensions, responsive delivery, descriptive context, and accessible alternatives work together. Use these guides after deciding why the image belongs on the page.
- Start with the image SEO checklist to review purpose, context, and discoverability.
- Use the responsive-sizes guide to understand why one oversized export is not appropriate for every screen.
- Measure the actual page after changing assets. Compression alone does not guarantee a Core Web Vitals pass or a ranking change.
