Which Markdown flavor does the converter support?

The converter supports CommonMark, the standardized Markdown specification. GitHub Flavored Markdown (GFM) adds tables, task lists, and strikethrough on top of CommonMark.

Does the HTML output include a full page structure?

No. The converter outputs only the body fragment (the converted content), not a full HTML document with doctype, head, or body tags. Wrap the output in a document template if you need a standalone HTML file.

How do I preserve syntax highlighting in converted code blocks?

The converter outputs elements for fenced code blocks. Syntax highlighting requires a client-side library like Prism.js or highlight.js to process these class names.

Convert Markdown to HTML

Markdown-to-HTML conversion is needed whenever Markdown content must be delivered as HTML — in emails where Markdown isn't rendered natively, in CMS platforms that accept HTML but not Markdown, in documentation generators that combine Markdown files with HTML templates, and in static site generators that render Markdown to HTML during the build process. Understanding what HTML each Markdown construct produces helps you debug rendering issues and write custom CSS to style the output. This example demonstrates all the fundamental Markdown constructs defined by CommonMark, the standardized Markdown specification. Each construct maps predictably to a specific HTML element: # Heading One becomes <h1>, ## Heading Two becomes <h2>, **bold** becomes <strong>, *italic* becomes <em>, backtick-wrapped text becomes <code>, link syntax [text](url) becomes <a href="url">, fenced code blocks become <pre><code>, and list items become <li> within <ul> or <ol> elements. Language identification in fenced code blocks: the ```javascript fence generates <pre><code class="language-javascript"> in most converters. This class name is the convention used by syntax highlighting libraries like Prism.js and highlight.js. To add syntax highlighting to converted Markdown, include the library's CSS and JavaScript, then call Prism.highlightAll() or hljs.initHighlightingOnLoad() after the HTML is rendered. Blockquote conversion: the > blockquote syntax becomes <blockquote> in HTML. Blockquotes typically receive distinct styling (left border, italics, slightly different background) in documentation themes. If the output will be embedded in a CMS, check whether the CMS strips blockquote elements or allows them — some CMS sanitizers treat blockquotes as HTML and require explicit allowlisting. Extended Markdown syntax beyond CommonMark: GitHub Flavored Markdown (GFM) adds tables, task lists (- [ ] item), strikethrough (~~text~~), and @mentions on top of CommonMark. Many Markdown converters support GFM extensions. If your output contains tables or task list checkboxes, verify that your chosen converter supports GFM extensions and that the output HTML renders correctly in your target environment. Output format: the converter produces an HTML fragment (the body content), not a complete HTML document. There is no <!DOCTYPE html>, <html>, <head>, or <body> element. If you need a standalone HTML file, wrap the fragment in a minimal HTML template with the appropriate charset and viewport meta tags. Real-world use cases: a static blog generator converts Markdown posts to HTML and injects them into page templates; a documentation site converter processes Markdown API docs into a structured documentation website; a newsletter tool converts Markdown email drafts to HTML for email clients that don't support Markdown natively. Tips: always sanitize converted HTML before inserting it into the DOM in a browser context. Markdown from user input can contain HTML that Markdown parsers pass through directly — use a library like DOMPurify to remove XSS-risky elements and attributes before rendering.
