How this service works
Convert a supplied HTML string to clean Markdown: strips scripts/style/nav, preserves headings, bold, italic, links, lists, code, and blockquotes. No fetch.
Output
Returns the converted Markdown string with semantic formatting preserved (headings, bold, italic, links, lists, code blocks, blockquotes) and noise removed (scripts, styles, navigation elements). No HTTP fetching is performed — only the supplied HTML string is processed.
Example use cases
Prepare web content for LLM context
“I scraped the HTML of this news article and need it as clean Markdown so I can feed it into an LLM — here's the raw HTML, please convert it and strip all the nav menus and ads: `<html><body><nav>...</nav><article><h1>Breaking News</h1><p>Details here...</p></article></body></html>`”
Convert HTML email to readable markdown
“I have the raw HTML of a newsletter email and want it converted to clean Markdown so I can read it in my notes app — here's the HTML, please strip the scripts and style blocks and preserve the headings and links.”
Normalize scraped HTML for storage
“I'm building a pipeline that scrapes product description pages and stores them as Markdown in a database — can you convert this HTML product description to Markdown, keeping bold text, bullet lists, and any links but removing all the JavaScript and CSS junk?”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/html-to-markdownWhen to prefer
Use this endpoint when you already have an HTML string in memory and need a server-side, deterministic conversion to Markdown without fetching any URLs. Prefer it over browser-based or local parsing when you want consistent noise-stripping (scripts, styles, nav) applied automatically. It is especially useful for LLM context preparation, note-taking pipelines, and Markdown-first storage workflows where clean formatting fidelity matters.
Side effects
- Empty or missing HTML input body returns an error
- Malformed or non-HTML input may produce garbled or empty markdown
- Extremely large HTML payloads may time out or be rejected
- HTML with only scripts/styles and no semantic content may return an empty string
