  • What Is a Markdown to HTML Converter?

    A Markdown to HTML converter transforms Markdown-formatted text into valid HTML. Markdown is a lightweight markup language that's easier to read and write than HTML, making it popular for documentation, README files, blog posts, and note-taking.

    Why Convert Markdown to HTML?

    While Markdown is great for writing, browsers render HTML. Converting Markdown to HTML lets you use Markdown's simple syntax for authoring content that will be displayed on the web. This is how most static site generators, documentation tools, and blogging platforms work internally.

    Supported Syntax

    • Headings: # through ###### for h1 through h6
    • Emphasis: *italic*, **bold**, ***bold italic***
    • Links: [text](url)
    • Images: ![alt](url)
    • Lists: - or * for unordered, 1. for ordered
    • Code: backticks for inline, triple backticks for blocks
    • Blockquotes: > prefix
    • Horizontal rules: ---

    Use Cases

    Convert README.md files to HTML for documentation sites. Transform blog post drafts written in Markdown into HTML for CMS platforms. Generate HTML email content from Markdown source. Preview how Markdown will render before committing to a repository.

    Privacy

    All conversion happens in your browser. Your text is never sent to any server.

    Minify the output with our HTML Minifier. Check heading structure with the Heading Structure Checker.

    Frequently asked questions

    What Markdown features are supported?

    Headings, bold, italic, links, images, unordered lists, blockquotes, code blocks, inline code, and horizontal rules.

    Is the output sanitized?

    The preview is sanitized using DOMPurify. The raw HTML output is the direct conversion — sanitize it in your application as needed.

    Can I convert HTML back to Markdown?

    This tool only converts Markdown → HTML. Reverse conversion requires different parsing logic.

    Does it support tables?

    Basic Markdown tables are not supported in this simplified converter. Use a full Markdown library for table support.
