🔍 How it works

The crawler follows internal links within the same domain as your Start URLs. On each page it extracts media from <img> (including srcset and data-src), <picture>, inline CSS backgrounds, <video>/<audio> and their <source> children, plus og:image, twitter:image and favicons. All URLs are resolved to absolute and de-duplicated per page. Pure HTTP — fast and inexpensive.

🧰 Tips & best practices

• Set maxPagesToCrawl to 0 to inventory an entire catalog or media library.
• Filter by mediaType or fileExtension after the run to get exactly the assets you need.
• Use imagesMissingAlt-style filtering: rows where alt is empty are your image-SEO fixes.
• To download the files, feed the mediaUrl list into a bulk downloader.

❓ FAQ

Does it download the image files? No — it extracts asset URLs and metadata. You can download them from the mediaUrl list afterwards with any bulk downloader.

Does it capture lazy-loaded images? Yes — it reads data-src, srcset and <picture> sources in addition to plain src.

Does it render JavaScript? No — it parses server-rendered HTML for speed and low cost.

How do I crawl the whole site? Set maxPagesToCrawl to 0.

What formats can I export? JSON, CSV, Excel, HTML and a full REST API.
