Website Image Analyzer
Enter a page URL and the system inspects its images (up to 12) — real size, format, WebP-converted size estimate, and per-image SEO/performance issues
How to use it
Enter a page URL
Use a published page that anyone can open without signing in — a home page or any other. It works on your own site and on someone else's.
The page gets fetched and measured
We read the page's HTML, collect its images, then download them and measure the real thing: file size, dimensions, format, and what a WebP conversion would leave.
Fix the heaviest images first
Results show which images cost the most bandwidth and which are missing alt or width/height. Take the originals to the compressor, then re-upload them.
Limits worth knowing
- Ten analyses per hour per IP address, because a single run downloads several real image files.
- Only <img> tags present in the page's HTML are read — CSS background images and images injected by scripts after load are not counted.
- Up to 12 images per page, in the order they appear; the rest are skipped.
- The page must be publicly reachable — LAN addresses, internal hosts and anything behind a login are refused up front.
- HTML is capped at 2 MB and each image at 8 MB; anything larger is skipped and reported in the count.
Frequently asked questions
How is this different from the image compressor?
The compressor works on files you already have and hands back smaller ones. This page looks at a site that is already published and tells you which of its live images are a problem. Use them together: find the problem here, fix it there.
Why are some images on the page missing from the results?
We only read the HTML the server sends. Images set as CSS backgrounds, images loaded later by JavaScript, and everything past the twelfth image will not appear.
How reliable is the savings figure?
It is a real conversion, not a formula: the image is encoded to WebP at quality 75 and the result measured — animated images excepted. Your own numbers will differ slightly depending on the settings you convert with.
Why do alt and width/height matter?
Alt text is what someone using a screen reader hears, and what search engines use to understand the image. Width and height let the browser reserve the space in advance, so the page does not jump around as images finish loading.
Can this replace a PageSpeed score?
No. This looks at images only — it does not measure real load time, scripts, fonts or CSS. Treat it as a to-do list for images you can act on today, not a full performance audit.
