Convert Markdown to HTML instantly
A Markdown to HTML converter transforms plain-text Markdown formatting into standard HTML markup. Markdown was created by John Gruber in 2004 as a lightweight alternative to writing raw HTML — instead of typing <h1>Title</h1>, you simply write # Title. This converter bridges the two: you write in Markdown's readable syntax and get clean, ready-to-use HTML output.
Markdown is widely used across the web. GitHub READMEs, technical documentation (Docusaurus, MkDocs, Hugo), note-taking apps (Obsidian, Notion), and content management systems (Ghost, WordPress) all rely on Markdown as a primary authoring format. Converting it to HTML is the standard step between writing content and publishing it on the web.
This tool uses CommonMark-compatible parsing rules, which means it handles headings, emphasis, lists, links, inline code, code blocks, blockquotes, and horizontal rules consistently. Unlike some converters, it preserves any raw HTML you include in your Markdown — so you can embed custom elements, iframes, or styled divs alongside standard Markdown syntax without losing them in the conversion.
The conversion happens entirely in your browser — your text never leaves your device. When you click Convert, the tool reads the Markdown from the input panel, applies a series of regex-based transformations, and renders the result as live HTML in the preview panel on the right.
Here's the processing order: headings are detected first (lines starting with #, ##, ###), then inline formatting like bold (**text**), italic (*text*), and inline code (`code`). Unordered list items (- item) are wrapped in <li> tags, and paragraph breaks are inserted at double newlines. Raw HTML within the Markdown passes through unchanged, so you can mix both syntaxes freely.
The Copy HTML button captures the rendered innerHTML from the preview panel and places it on your clipboard. You can then paste it directly into a CMS, email template, or static HTML file. No server processing, no API calls — everything runs client-side for speed and privacy.
Get clean, predictable HTML output:
<div class="note">). The converter preserves it — useful when you need markup markdown doesn't support.**_text_**) usually works, but complex nesting can confuse parsers. If the output looks wrong, simplify the nesting.This tool fills the gap between writing and publishing:

There are many ways to convert Markdown to HTML — from command-line tools like Pandoc to online converters. Here's why this tool stands out:
Markdown and HTML serve different purposes. Here's when to use each:
Use Markdown when: You want to focus on writing without worrying about tags. It's perfect for drafting blog posts, documentation, notes, and content that will be converted to HTML later.
Use HTML when: You need precise control over layout, styling, forms, or interactive elements. HTML gives you full access to all web capabilities, but requires more typing and attention to closing tags.
Best of both worlds: This converter lets you write in Markdown's simplicity and get HTML's flexibility. Write your content in Markdown, convert it, then tweak the HTML if needed. You can even mix raw HTML into your Markdown input — the converter preserves it in the output.
Headings (#), bold (**), italic (*), lists (- or 1.), links, code blocks, blockquotes, and horizontal rules.
Yes, click "Copy HTML" to copy the raw HTML code to clipboard.
No. All conversion happens in your browser. Your Markdown text is never uploaded or stored anywhere — the tool works entirely offline.
The converter supports standard CommonMark syntax including headings, emphasis, lists, links, code, and blockquotes. GitHub-extended syntax like tables and task lists are not currently supported, but you can embed raw HTML tables directly in your Markdown input.
No, this tool only converts Markdown to HTML. For HTML-to-Markdown conversion, you would need a different tool or a library like Turndown.js. The reason is that HTML has many features (forms, scripts, complex nesting) that don't have Markdown equivalents.
Yes! This converter does not sanitize or strip raw HTML. If you include HTML tags in your Markdown input (like <div class="callout">), they will appear unchanged in the HTML output. This lets you mix Markdown's simplicity with HTML's full power.
The converter outputs clean HTML without inline styles. You can apply your own CSS by wrapping the output in a styled container, or by adding a <style> block. For email newsletters, you may need to inline CSS using a separate tool for maximum compatibility.
Yes. The generated HTML uses standard tags (<h1>-<h6>, <p>, <strong>, <em>, <code>, <ul>, <blockquote>) that work in all major CMS platforms. Simply paste the output into the HTML view of your editor.
Not all Markdown is created equal. The original specification (CommonMark) defines the core syntax: headings, paragraphs, emphasis, lists, code spans, and links. But most modern platforms extend this with their own "flavors" — added features for tables, task lists, footnotes, and more.
GitHub Flavored Markdown (GFM) is the most widely used extension set. It adds tables, task lists (- [x]), strikethrough (~~text~~), auto-linked URLs, and syntax highlighting in fenced code blocks. This tool supports all GFM features except auto-linked URLs (which you can manually create with [text](url)).
Other flavors include MultiMarkdown (footnotes, definition lists, tables), Pandoc Markdown (citations, raw TeX, custom blocks), and Kramdown (used by Jekyll). If you're writing for a specific platform, check which flavor it supports — then use this converter to transform your content into clean HTML.
Yes. The converter supports tables, task lists, strikethrough, and fenced code blocks with syntax highlighting markers. These are converted to clean HTML (<table>, <ul class="task-list">, <del>, <pre><code>) that you can style with CSS.
This tool is Markdown → HTML only. For HTML → Markdown, try our HTML to Markdown converter. The two tools together cover the full round-trip conversion workflow.
You can include raw HTML with class attributes in your Markdown (e.g., <div class="highlight">content</div>), and it will pass through unchanged. For bulk styling, target the standard tags in your CSS: preview h1, preview code, etc.
The input is limited only by your browser's memory. For typical documents under 1MB, conversion is instant. Very large documents (10,000+ lines) may take a few seconds. There is no server-side limit because nothing is sent to a server.
Yes, the output HTML works in email clients that support standard HTML tags. Avoid complex CSS (flexbox, grid) as some email clients strip them. Use inline styles for best compatibility across email providers.
This tool covers the core CommonMark specification (headings, emphasis, lists, links, code). For GFM-specific features like tables, task lists, and strikethrough, the output will include the raw text. For full GFM support, consider using a dedicated GFM parser or our Markdown Preview tool.
By default, Markdown condenses multiple line breaks into one. To force a line break, add two spaces at the end of a line or use a backslash \ before the newline. The converter respects these and outputs <br> tags accordingly.
This tool processes one document at a time in the browser. For batch conversion, you can sequentially paste and convert multiple documents, or use a command-line tool like Pandoc for offline batch processing. Each conversion here is instant and private.
CMS platforms (WordPress, Ghost, Webflow) often add their own CSS styles that override or complement the converted HTML. The output from this tool is clean, semantic HTML — how it renders depends on the CSS of the target platform. Use the Copy HTML button and paste into your CMS's HTML view for best results.
Want cleaner, more semantic HTML? Here are some tips:
# H1, ## H2, ### H3 in order. Don't skip heading levels. — the alt text will be preserved in the HTML alt attribute for accessibility.```) for proper tags instead of inline .
| Header |) for Markdown tables — they convert to proper HTML.
- Link wisely: Use descriptive link text (
[descriptive text](url)) instead of pasting raw URLs for better accessibility and SEO.
Pro tip: After converting, use the Copy HTML button and paste into an HTML validator (like W3C Markup Validation Service) to check for any issues before publishing.
Common Use Cases
Documentation & READMEs: Most open-source projects use Markdown for their documentation. Converting Markdown to HTML lets you preview exactly how your README or docs will render on platforms like GitHub, GitLab, or your own documentation site.
Blogging & Content Creation: Many writers draft in Markdown for its simplicity, then convert to HTML for their blog platform (WordPress, Ghost, Medium). This tool gives you clean HTML output that preserves your formatting.
Note-Taking & Knowledge Bases: Obsidian, Notion, and similar tools use Markdown. When you need to publish your notes as a webpage, converting to HTML is the fastest path.
Email Newsletters: Some newsletter platforms accept HTML directly. Write your newsletter in Markdown, convert it, and paste the HTML into your email tool for a professionally formatted message.
Static Site Generators: Hugo, Jekyll, and Eleventy all use Markdown for content. Converting to HTML lets you preview how your content will look before building the site.
Technical Documentation: API docs, wikis, and developer portals often use Markdown. Converting to HTML helps you verify the output matches your platform's rendering.
Collaborative Writing: When working with non-technical teammates who don't know Markdown, convert to HTML so they can preview the formatted document in any browser without installing tools.
Pro Tips for Better HTML Output
- Use Semantic HTML: Markdown produces clean semantic tags (
<h1>-<h6>, <p>, <ul>, <blockquote>). This is great for SEO and accessibility.
- Preview Before Publishing: Always preview the HTML output in a browser to ensure formatting matches your expectations, especially for nested lists and code blocks.
- Combine with CSS: The converted HTML is unstyled. Add your own CSS to match your site's design — target the tags directly or add custom CSS classes in your Markdown.
