Enter a URL — it pulls a PageSpeed Insights audit and loads the page in a real browser to measure every image's actual rendered size, then shows the bytes you can save by resizing + WebP. Optimized images ready to download.
Tip: paste a product or landing page — that's where oversized hero images usually hide.
PageSpeed Insights data is unavailable for this run, so the speed grade below is image-only. On image weight specifically, you're shipping 13.0 MB (95%) more than needed across 56 images — resizing to display size + WebP is the quickest win below.
Cut 13.0 MB of image weight (resize to render size + WebP) — see the table below.
