Markdown to HTML Converter
Convert Markdown text to HTML. Paste your Markdown and get clean HTML output instantly.
What This Tool Does
The Markdown to HTML converter takes Markdown syntax — the lightweight markup language used in README files, documentation, note-taking apps, and static site generators — and outputs clean, semantic HTML. The conversion follows the CommonMark specification with GitHub Flavored Markdown (GFM) extensions, covering headings, bold, italic, links, images, tables, code blocks, and task lists. To preview the rendered output before converting, use the Markdown Preview tool.
Markdown was designed to be readable as plain text, but HTML is what browsers and content management systems need for rendering. This tool bridges that gap instantly — paste Markdown, copy HTML, done.
Common Uses
Converting README.md content to HTML for embedding in a web page. Generating HTML from documentation written in Markdown before publishing to a CMS. Extracting clean HTML from Markdown for use in email templates where the email client needs HTML, not Markdown. Testing that Markdown renders correctly to HTML before committing to a repository.
Code Blocks and Syntax Highlighting
Fenced code blocks (```language) are converted to <pre><code class="language-NAME"> output. This is the format expected by syntax highlighting libraries like Prism.js and Highlight.js — add either library to your page and the code blocks will be automatically highlighted using the language specified in the fence.
💡 For a live preview of your Markdown before converting, use the Markdown Preview editor. If the resulting HTML needs to be minified for production, the HTML Formatter handles both formatting and minification.
