Website Images Extractor
Every image with alt text and format
What Is the Website Images Extractor?
The Website Images Extractor renders a page, including lazy-loaded images, and lists every image with a preview, its URL, alt text, dimensions and file format. It flags images with no alt attribute and shows how many use modern formats like WebP and AVIF.
Key Features
Image SEO in One Glance
Images drive a lot of page weight and a fair share of search traffic through Google Images. Alt text tells search engines and screen readers what an image shows. Modern formats like WebP and AVIF cut file sizes sharply, and declared dimensions stop the layout from jumping as the page loads.
What It Finds and What It Misses
The extractor collects every <img> element after the page has rendered, which covers lazy-loaded images. Background images set in CSS aren't included, since they aren't part of the page's image markup. Very large galleries that load more images as you scroll may only show the first batch.
Common Use Cases
- Finding images with missing alt text
- Checking whether a site uses modern image formats
- Collecting a page's image URLs
- Auditing image dimensions for layout shift
Frequently Asked Questions
Is the Website Images Extractor free?
Yes. It's free with a ProxyHorizon account, and every account gets 25 runs a day shared across all our data tools. You can read about the tool without signing in, but running it needs an account because each run fetches live data.
What is the difference between missing and empty alt?
A missing alt attribute is an error. An empty alt (alt="") tells screen readers to skip a decorative image, which is correct.
Can I download the images?
Export the list of image URLs as CSV or JSON. Only reuse images you have the rights to.
Does it find CSS background images?
No. It lists <img> elements, which covers most content images.
