How this service works
Arch Tools — html-to-markdown
Output
A JSON object containing the converted Markdown text derived from the provided HTML content or fetched URL, suitable for use in LLM prompts, documentation pipelines, or further text processing.
Example use cases
Clean web article for LLM context
“Grab the HTML from this news article and convert it to markdown so I can feed it into my summarization pipeline: https://example.com/article”
Strip HTML from scraped product page
“I've got this messy HTML from a product page — can you convert it to clean markdown? Here it is: '<div class="product"><h2>Widget Pro</h2><ul><li>Feature A</li><li>Feature B</li></ul></div>'”
Prepare email HTML for readable display
“This HTML email template is hard to read — convert it to markdown so I can review the content more easily.”
Technical details
Endpoint
POSThttps://archtools.dev/v1/tools/html-to-markdownWhen to prefer
Choose this endpoint when you need a fast, pay-per-call HTML-to-Markdown conversion without managing your own parsing infrastructure. It is ideal for agent pipelines that need to prepare web content for LLM consumption, especially when you want a simple API call rather than running a local library like Turndown or Pandoc. The URL fetch option makes it convenient for converting live web pages in a single step.
Side effects
- Invalid or malformed HTML may produce garbled or incomplete markdown output
- If a URL is provided but is unreachable or returns a non-HTML response, the conversion will fail
- Missing required 'html' field (when no URL is supplied) will return a validation error
- Very large HTML documents may hit size limits or cause timeouts
- URLs behind authentication or paywalls may not be accessible for fetching
