Why Convert HTML to Markdown?
Markdown has become the preferred format for feeding documents into large language models and retrieval-augmented generation (RAG) systems. Unlike HTML, which is cluttered with tags, attributes and styling, Markdown represents the same content in a clean, token-efficient form that models can parse more predictably.
Cleaner Input for LLMs
HTML carries a lot of markup that adds noise without adding meaning. Converting to Markdown strips away the noise while preserving structure such as headings, lists, links and code — which helps language models understand the document hierarchy and reduces token waste.
Better RAG Chunking
RAG pipelines often split documents into chunks before indexing. Markdown's predictable structure — headings, paragraphs and lists — makes it much easier to chunk content semantically than raw HTML.
Works Entirely Locally
This converter runs fully in your browser using the built-in DOM parser. Your content is processed on your device and is never uploaded to a server, making it suitable for sensitive or internal documents.

The converter handles the most common HTML elements:
- Headings (h1–h6) with ATX or Setext style
- Paragraphs, line breaks and horizontal rules
- Bold, italic, strikethrough and inline code
