HTML Asset, Image & Markdown Extractor

Analyze raw HTML for scripts, stylesheets, images, and links. Includes inline background-image URLs from HTML style attributes and style tags — also pulls the page's visible text out as clean Markdown, handy for reading articles behind simple client-side paywalls.

Algorithmic Parsing of Document Object Models 🖖

Extracting embedded assets from HTML requires recursive traversal of the Document Object Model tree structure. By utilizing precise regular expressions and tag-specific targeting, the algorithm segregates image URIs and structural elements. It then algorithmically converts hierarchical nodes into equivalent Markdown syntax. This systematic reduction process efficiently transforms a complex, nested presentation language into a streamlined, logically ordered plain-text mathematical structure.

Images hide in more than img tags 🖖

Most people assume a web image always lives in an `<img>` tag, but browsers also paint pictures from CSS `background-image` rules, responsive `srcset` lists, `<meta>` social-preview tags, and even arrays inside JavaScript. This tool sweeps all of those places at once. The practical takeaway: a photo you plainly see on screen may have no `<img>` tag at all — it is drawn by a stylesheet, which is why 'right-click, save image' sometimes fails.

A soft paywall hides text it already sent 🖖

Many 'subscribe to keep reading' walls are pure theatre. The full article is usually delivered in the page's HTML and then merely covered by an overlay or blur — the words crossed the network before you were asked to pay. Because this extractor reads the visible text straight from the parsed markup as Markdown, that content reappears intact. It is a reminder that hiding something with CSS is not the same as withholding it.

Example problems

responsive gallery - Landing page with a schema.org ImageObject JSON-LD block and a responsive <img srcset> — shows structured-data image extraction plus dedup of same-image resolution variants.
CSS backgrounds - Page whose only images live in CSS background-image declarations — one inside a <style> block, one in an inline style attribute — the kind of asset a plain <img> scan would miss.
JS-rendered slider - Image slider built entirely at runtime by JavaScript, with no <img> tags in the markup — shows how the extractor recovers image URLs from a plain JS array literal inside a <script> block.
