Convert Markdown text to HTML instantly in your browser using marked.js. Optionally wrap the output in a complete HTML document for direct publishing.
This converter uses marked.js (v9.1.6) to parse Markdown text and produce HTML output. marked.js is one of the fastest and most widely-deployed JavaScript Markdown parsers, used by projects including Gatsby, Docusaurus, and thousands of npm packages. It fully supports the CommonMark specification and GitHub Flavored Markdown (GFM) extensions including tables, strikethrough, and task lists.
By default, this converter outputs only the HTML fragment (the body content). This is the correct format when you are inserting the output into an existing HTML page or CMS. Enable "Wrap in full HTML document" to generate a complete, standalone HTML file with <!DOCTYPE html>, <head>, and a minimal embedded stylesheet — suitable for downloading and opening directly in a browser or sharing as a self-contained HTML document. Write and edit Markdown first in our markdown editor online with live preview. If you need to go the other way, our HTML to Markdown converter converts existing HTML pages back to Markdown syntax.
The "Convert line breaks" option controls whether single newlines within a paragraph are rendered as <br> tags. With the option enabled (default), a single Return in your Markdown creates a line break in the HTML output — matching the behaviour of GitHub, Slack, and many chat platforms. With it disabled, a single newline is treated as a space (standard CommonMark behaviour), requiring a blank line to separate paragraphs.
Yes. Tables are a GFM (GitHub Flavored Markdown) extension supported by marked.js with the gfm: true option (enabled by default). Use the pipe | character to define columns and a row of --- dashes to separate the header from the body rows. Example:| Col 1 | Col 2 || ----- | ----- || Data | Data |
Install the markdown library: pip install markdown. Then: import markdown; html = markdown.markdown(text). For GFM features (tables, fenced code blocks), install pip install markdown pymdown-extensions and use extensions=['tables','fenced_code'] in the markdown() call.
Yes. All conversion happens in your browser using JavaScript. Your Markdown text is never sent to any server and never leaves your device. This tool is safe for converting confidential documents or proprietary technical content.
