How to Convert Markdown to HTML
Write or Paste Markdown
Enter your Markdown text in the left panel. Use standard Markdown syntax — headings with #, bold with **, lists with -, links with [](), and code with backticks.
Click Convert
The converter processes your Markdown and outputs clean, semantic HTML in the right panel. The HTML uses standard tags like <h1>, <strong>, <ul>, <pre>, and <blockquote>.
Preview or Copy
Use the Preview button to see how the HTML renders visually. Copy the HTML output to paste into your CMS, blog, email template, or code project.
What Is Markdown?
Markdown is a lightweight markup language created by John Gruber in 2004 with the goal of being readable as plain text while still convertible to valid HTML. The syntax uses intuitive character patterns: asterisks for emphasis, hashes for headings, hyphens for lists, and brackets for links. Its readability is what made it the default writing format for GitHub, Stack Overflow, Reddit, Discord, and countless documentation platforms.
The conversion from Markdown to HTML is straightforward but involves nuanced parsing. A single asterisk wraps
text in <em> tags (italic), double asterisks produce <strong> (bold),
and triple asterisks combine both. Headings use one to six hash marks corresponding to
<h1> through <h6>. Code blocks wrapped in triple backticks become
<pre><code> elements. Lists automatically detect whether they're ordered (numbered)
or unordered (bulleted).
For developers and technical writers, Markdown eliminates the friction of writing HTML by hand. You get the semantic structure of HTML with the writing experience of plain text. READMEs, API documentation, blog posts, changelogs, and wiki pages are all commonly authored in Markdown and then converted to HTML for web display.
Our converter handles the complete CommonMark specification: headings (h1-h6), bold/italic emphasis, ordered and unordered lists, links, images, blockquotes, inline code, fenced code blocks, horizontal rules, and line breaks. The output is clean, valid HTML that you can paste directly into any web page or template.

Frequently Asked Questions
The converter supports the core Markdown specification: headings (#-######), bold (**text**), italic (*text*), links ([text](url)), images (), unordered lists (- item), ordered lists (1. item), blockquotes (> text), inline code (`code`), fenced code blocks (```), horizontal rules (---), and line breaks. It covers the great majority of Markdown content you'll encounter.
This tool is designed for one-way conversion: Markdown → HTML. HTML to Markdown is a much more complex transformation because HTML has many ways to express the same formatting. Dedicated HTML-to-Markdown converters exist, but they often produce imperfect results because of the fundamental differences in how the two formats represent structure.
The preview renders the HTML with browser default styling, which includes proper heading sizes, bullet points, code formatting, and blockquote indentation. The visual output shows what your content will look like on a basic web page without custom CSS applied.
Absolutely — that's one of the primary use cases. Write your blog post in Markdown for readability, convert to HTML, and paste into your CMS's HTML editor. This workflow is faster than using a WYSIWYG editor and produces cleaner HTML. Many professional bloggers and technical writers use this exact workflow.
Our converter handles basic Markdown table syntax with pipe (|) delimiters and alignment rows. While tables aren't part of the original Markdown specification, they're included in the GitHub Flavored Markdown extension and are widely used. The converter produces standard HTML table markup from Markdown table input.
