HTML to Markdown
Paste HTML, get clean Markdown — headings, lists, tables, links, and code preserved.
How to convert HTML to Markdown
- Open the HTML page in your browser, right-click the content, and choose "Inspect" or "View page source"
- Copy the HTML from inside the <body> or <article> tag
- Paste it below and click Convert
- Or paste a snippet directly from any source — the tool handles partial HTML fine

How does the HTML to Markdown converter work?
The converter walks your HTML and replaces every standard HTML element with the equivalent Markdown syntax. Headings (<h1> through <h6>) become #, ##, ### prefixes. Lists become hyphen or numbered lists. Tables become Markdown pipe tables. Links keep their anchor text and href. Bold and italic emphasis are preserved.
It runs entirely in your browser — your HTML never leaves the page, never hits a server, and there is no rate limit. Paste 200KB of source and it handles it in milliseconds.
For LLM and RAG use cases, the converter strips <script> and <style> tags first so they do not pollute the output. The result is the kind of clean, structured Markdown that knowledge-base ingestion pipelines expect.
Why convert HTML to Markdown instead of keeping it as HTML?
Markdown is shorter, more portable, and far easier to edit by hand. The same article in HTML often takes 2-3x as many bytes as in Markdown — and HTML is hostile to humans editing it. Markdown reads naturally even when you have not rendered it.
For LLM training and retrieval-augmented generation, Markdown is also the format most ingestion pipelines prefer. The structure (headings, lists, tables) survives chunking and embedding far better than raw HTML, which often gets stripped to plain text and loses all the hierarchy that makes retrieval accurate.
What HTML elements does this converter support?
The converter handles every common HTML element you will find in articles, documentation, and product pages: headings h1-h6, paragraphs, line breaks, horizontal rules, ordered and unordered lists (with nesting), bold and italic emphasis, inline code and code blocks, blockquotes, links, images, tables (header row plus body rows), and the &, <, >, ", ', HTML entities.
It does not currently render: collapsible <details>/<summary>, definition lists, or non-standard custom HTML elements. If you have HTML with those, the converter will strip them down to the inner text.
Can I use HTML to Markdown for AI knowledge bases?
Yes — and this is one of the strongest use cases. Most AI knowledge-base ingestion pipelines (Hyperleap AI included) work better with Markdown than with raw HTML, because the structure of headings and lists tells the chunker where logical boundaries are.
Once you have clean Markdown, you can drop it into your Hyperleap AI agent's knowledge base. Markdown is the format Hyperleap parses best for RAG — it preserves structure (headings, lists, tables) and keeps file sizes small. For best results, convert each HTML page to its own Markdown file, keep the file under ~10KB if possible, and use sensible H2/H3 headings for the sections you want the agent to retrieve independently.
