Webpage to Markdown Converter
Convert any webpage to clean Markdown instantly. Enter a URL or paste HTML source and download a .md file ready for AI tools, LLMs, or documentation. Free, browser-based.
The Webpage to Markdown Converter turns any webpage into clean, readable Markdown — the format preferred by AI assistants, LLMs, vector databases, and documentation systems. Whether you are building a knowledge base for an AI chatbot, feeding context into a language model, creating offline documentation, or simply want a portable, plain-text version of an article, this tool gives you a structured Markdown file in seconds.
There are two input modes. In URL mode, enter the full address of any publicly accessible webpage and the tool fetches the HTML via a CORS proxy and converts it on the fly. This works well for blog posts, documentation pages, news articles, and marketing pages. In Paste HTML mode, copy the page source directly from your browser (right-click → View Page Source → select all → paste) and convert it locally — useful for pages behind login walls, paywalls, or sites that block automated access.
The HTML-to-Markdown conversion happens entirely in your browser. The converter intelligently identifies the main content area of the page — looking for <main>, <article>, or common content class names — and strips away navigation menus, headers, footers, sidebars, scripts, and style blocks. What remains is converted to semantic Markdown: headings become # through ######, bold and italic text is preserved, links are rendered as [text](url), images as , code blocks as fenced triple-backtick blocks with language labels, lists (ordered and unordered, including nested), blockquotes, and tables formatted as Markdown pipe tables.
The resulting Markdown is displayed in a large text area where you can review it before use. Copy it to your clipboard with one click, or download it as a .md file named after the source domain. The file is ready to drag into ChatGPT, Claude, Notion, Obsidian, a vector store, or any tool that accepts Markdown or plain text input.
All link and image URLs are validated before rendering — only http and https sources are included as active links; javascript: and data: URIs are stripped for safety. The converter does not store any content you enter, and page HTML is never transmitted to our servers.
Frequently Asked Questions
- Why convert a webpage to Markdown for AI use?
AI assistants and LLMs work best with clean, structured plain text. Raw HTML contains thousands of characters of noise — scripts, styles, navigation, ads — that consume context window tokens without adding meaning. Markdown preserves the semantic structure (headings, lists, emphasis, code) while removing the noise, giving the model cleaner signal and letting you fit more content into a single prompt or vector embedding.
- What happens when a URL does not load?
Some websites block automated fetching (bot protection, CORS restrictions, login walls, or paywalls). When that happens you will see an error message. Switch to
- Which page elements are kept and which are removed?
The converter keeps: headings, paragraphs, bold/italic/strikethrough text, inline code, code blocks with language labels, blockquotes, ordered and unordered lists (including nested), tables, links (http/https only), and images (http/https only). It removes: navigation menus, headers, footers, sidebars, scripts, stylesheets, forms, buttons, iframes, SVGs, and ads. The converter also tries to identify the main content container (<main>, <article>, or common CMS class names) before converting, so surrounding chrome is usually eliminated automatically.
- Is my content sent to your servers?
The HTML-to-Markdown conversion itself runs entirely in your browser — no content is ever sent to our servers. When you use URL mode, the page HTML is fetched through a public CORS proxy because browsers block direct cross-origin requests from JavaScript; the tool tries corsproxy.io first, and automatically falls back to api.allorigins.win and then api.codetabs.com if the first proxy is unavailable or blocked by the target site. Each proxy simply forwards the requested page\
- Can I convert multiple pages at once?
The tool processes one page at a time. For batch conversion of many pages, you would need a server-side script or a CLI tool. For single pages — articles, documentation pages, blog posts, landing pages — the URL or paste workflow handles it in a few seconds per page.
