Markdown to HTML

How to convert Markdown to HTML?

Converting Markdown to HTML is straightforward with this real-time converter. The tool parses your Markdown input and generates clean, semantic HTML5 output:

• Paste or type your Markdown text into the left input panel. You can include any standard Markdown elements: headings (# through ######), bold (**text**), italic (*text*), strikethrough (~~text~~), unordered lists (- or *), ordered lists (1. 2.), blockquotes (>), inline code (`code`), fenced code blocks (```language), links ([text](url)), images (), horizontal rules (--- or ***), and tables using pipe notation.
• Watch the HTML output render in real-time in the right panel as you type. The converter processes your Markdown continuously, updating the HTML output with every change. This live preview lets you see exactly how your Markdown will appear as HTML before you copy the result.
• Review the generated HTML for correctness. The converter produces semantic HTML5 elements: headings map to <h1>-<h6>, bold becomes <strong>, italic becomes <em>, links become <a href="">, images become <img src="">, code blocks become <pre><code>, and tables become <table> with proper <thead>, <tbody>, and <tr> structure. Check that nested elements like lists inside blockquotes or links inside bold text rendered correctly.
• Copy the HTML output using the Copy button, or download it as a standalone .html file. The generated HTML is self-contained and can be pasted directly into CMS editors, static site generators, email templates, or any system that accepts raw HTML markup.

Understanding the Markdown-to-HTML mapping

Markdown was designed as a human-readable format that maps predictably to HTML. Each Markdown construct has a direct HTML equivalent: # heading becomes <h1>, **bold** becomes <strong>, *italic* becomes <em>, > quote becomes <blockquote>, ```code``` becomes <pre><code>, and - list item becomes <li> wrapped in <ul>. Understanding this mapping helps you predict the output and troubleshoot rendering issues. For instance, indentation matters critically for nested structures — a list item indented under another list item creates a nested <ul> inside <li>, while a paragraph indented under a blockquote keeps the paragraph inside the <blockquote>. Code blocks preserve whitespace exactly as written, which is why indentation inside <pre><code> blocks is maintained faithfully. Tables require consistent column alignment in the Markdown source; misaligned pipes create malformed table cells in the HTML output. The converter follows CommonMark specification rules for edge cases like blank lines between elements, trailing spaces affecting line breaks, and escaped characters that suppress Markdown formatting.

GitHub Flavored Markdown extensions supported

Beyond standard Markdown, this converter supports several GitHub Flavored Markdown (GFM) extensions that are widely used in modern documentation workflows. Tables use pipe-delimited syntax with a header separator row: | Header 1 | Header 2 | followed by | --- | --- | and data rows. Task lists use the checkbox syntax: - [ ] for unchecked items (rendered as <input type='checkbox' disabled>) and - [x] for checked items. Strikethrough uses double tildes: ~~deleted text~~ renders as <del> or <s>. Autolinks recognize bare URLs and convert them automatically: https://example.com becomes <a href='https://example.com'>. Fenced code blocks support language identifiers for syntax highlighting hints: ```javascript produces <code class='language-javascript'>. These extensions make the converter compatible with README files from GitHub, GitLab, and other platforms that use GFM. Note that some GFM features like footnotes and definition lists are not universally supported and may not be included in this converter's output.
