Markdown to HTML Converter

How to Use the Markdown to HTML Converter

Type or paste your Markdown content into the top text area. The converter processes it in real time, producing clean HTML in the output area and a rendered preview below it. The HTML uses semantic tags that work in any web page, email client, or content management system. Click "Copy HTML" to grab the output.

The converter recognizes the most widely used Markdown elements: headings from level one through six, bold and italic text, strikethrough, inline code and fenced code blocks, links, images, ordered and unordered lists, blockquotes, horizontal rules, and pipe-delimited tables. Fenced code blocks accept a language identifier after the opening backticks, which produces a class attribute compatible with syntax highlighting libraries.

Why Markdown Became the Writing Standard for Developers

John Gruber created Markdown in 2004 with a single goal: let people write using a plain-text format that is easy to read as-is and can be converted to structurally valid HTML. It caught on because the syntax is genuinely intuitive. A heading looks like a heading with a hash sign in front. Bold text sits between double asterisks. Lists start with dashes. You do not need to know HTML to write Markdown, but the output is proper HTML that browsers render correctly.

Today Markdown is the default format for README files on GitHub and GitLab, documentation in static site generators like Jekyll, Hugo, and Eleventy, issue trackers, wikis, developer blogs, and messaging platforms like Slack and Discord. Learning Markdown is a one-time investment that pays off across dozens of tools because the syntax is essentially the same everywhere, with minor dialect differences.

Common Markdown Syntax at a Glance

Headings use hash marks: one for h1, two for h2, up to six for h6. Emphasis wraps text in single asterisks for italics, double for bold, triple for bold italic. Links follow the pattern [text](url) and images use ![alt](src). Unordered lists start each line with a dash, plus, or asterisk. Ordered lists start with a number and a period. Code spans use backticks and code blocks use triple backticks. Blockquotes prefix lines with a greater-than sign. Tables use pipes and dashes.

When You Need the Raw HTML

Content management systems, email template builders, and static page generators sometimes require raw HTML rather than Markdown source. This converter bridges that gap. Write your content in Markdown, where it is easy to read and edit, then generate the HTML when you need it for final output. The resulting markup uses clean, standard tags with no unnecessary attributes or wrapper divs, which means it picks up whatever CSS styles your target page applies.

Frequently Asked Questions

What Markdown syntax does this converter support?

Headings, bold, italic, bold+italic, strikethrough, inline code, fenced code blocks with language hints, links, images, unordered and ordered lists, blockquotes, horizontal rules, tables, and paragraphs. It covers most CommonMark and GitHub Flavored Markdown features.

Is the conversion done on a server?

No. Everything runs in your browser. No data is transmitted. The tool works offline.

Can I use the generated HTML in my website?

Yes. The output is semantic HTML using standard tags. Copy and paste it into any page, template, or CMS.

Does the converter sanitize the output?

Special characters in your Markdown are escaped, so angle brackets and ampersands appear as literal text rather than being interpreted as HTML tags.

How are code blocks handled?

Fenced code blocks are wrapped in pre and code tags. Specifying a language adds a class for syntax highlighting compatibility.
