Free Markdown to HTML Converter
Convert Markdown to clean HTML in your browser. Type or paste Markdown on the left and the equivalent HTML source appears on the right as you type, with a rendered Preview one click away. Everything runs locally, nothing is uploaded.
What gets converted
Headings H1 to H6, bold, italic, strikethrough, inline and fenced code with syntax highlighting for common languages, links, images, ordered and unordered lists, GFM task lists with checkboxes, tables with column alignment, blockquotes, horizontal rules, footnotes, and inline or display math written between dollar signs. Raw HTML in the input is kept only where the sanitizer allows it, and script tags never survive.
Two output views
Raw HTML shows the generated source, ready to paste into a CMS, an email template, or a static page. Preview renders the sanitized HTML as a visitor would see it, including highlighted code and typeset math. Switch views with the tabs above the output.
Copy and download
Copy moves the Markdown source or the generated HTML to the clipboard. The .md download saves your source file, and the .html download produces a standalone page with minimal styles that you can open or publish as is.
Input options
Auto Update converts while you type; turn it off and press Convert (or Ctrl+Enter, Cmd+Enter on Mac). Upload a .md, .markdown, or .txt file up to 1 MB, insert the built-in Example to see the supported syntax, or Clear to start over. Character, word, and line counts update with the input, the A+ and A- buttons adjust each panel’s font size, and both panels have a fullscreen mode.
Example
Input:
# Hello
This is **bold** with `code`.Output:
<h1>Hello</h1>
<p>This is <strong>bold</strong> with <code>code</code>.</p>Good to know
Input is capped at 200,000 characters. The conversion libraries (marked, DOMPurify, highlight.js, KaTeX) load from a CDN, so the page needs a connection when it first loads; the conversion itself happens on your device. Math covers the subset KaTeX supports, and emoji shortcodes are not converted.
