All images use legacy JPG or PNG instead of WebP or AVIF

WebP and AVIF are modern image file formats that display at the same visual quality as JPG and PNG but at a significantly smaller file size — typically 30 to 50 percent smaller. Large images are one of the most common reasons websites load slowly, particularly on mobile. Slow page loads hurt search rankings, increase bounce rates, and frustrate visitors before they even read your content. Ask your web developer to convert existing images to WebP format and configure the site to serve these modern formats going forward. Most website platforms and image tools support this conversion automatically.
