Preparing Images for Google PageSpeed Checks

Common warnings

Page-speed reports often recommend properly sizing images, serving next-gen formats, and reducing unused bytes. These warnings usually mean the uploaded file is larger or heavier than the page needs.

Practical fixes

Resize images to match layout dimensions, compress photos, and consider WEBP for modern sites. Use responsive image markup in your website platform when possible so mobile visitors do not download desktop-sized assets.

Measure after changes

After replacing images, run another speed check and compare real page behavior. The goal is not just a perfect score; it is a faster, clearer experience for visitors.
