About Markdown Converter
Markdown has become the de facto standard for writing technical documentation, README files, blog posts, and knowledge base articles. Its lightweight syntax — asterisks for bold, hashes for headings, backticks for code — produces clean HTML without the overhead of a rich text editor. But to see exactly how Markdown will render, you need a live preview that processes it in real time.
Our Markdown Converter provides a split-pane editor where you write on the left and see the rendered HTML preview on the right, updating as you type. It covers the GitHub Flavored Markdown (GFM) essentials — tables, task lists that render as real checkboxes, strikethrough, fenced code blocks, blockquotes, nested lists, links and images — and colours fenced code blocks by language, with JavaScript, TypeScript, JSX, TSX, JSON, Python, Bash, SQL, YAML, HTML and CSS all recognised. The rendered output closely matches how your content will look on GitHub, Notion, and most modern documentation platforms. Footnote syntax ([^1]) is the one common extension it does not implement — it comes through as plain text.
The ".html" export generates a standalone document with the Markdown styles embedded in its head, making it portable for use in email campaigns, static HTML pages, or CMS systems that accept raw HTML. The exported markup is clean and semantic and works without any external stylesheet or JavaScript: syntax colouring lives in the preview, while the export keeps each code block's class="language-x" so your own site's highlighter can take over. There is a ".md" button too, for saving the source you just wrote.
How to Use Markdown Converter
- 1Type or paste your Markdown content into the left editor panel.
- 2The right panel updates in real time showing the rendered HTML preview.
- 3Use the ten toolbar buttons for common formatting — Bold, Italic, Heading, Link, Image, inline code, code block, blockquote, list, and a ready-made GFM table. Select text first and the button wraps it.
- 4Flip the right panel between "Preview" and "HTML" to inspect the exact markup you are about to copy.
- 5Click "Copy HTML" to copy the rendered HTML markup to your clipboard.
- 6Click the ".html" button to save the output as a standalone HTML file, or ".md" to save the Markdown source.
- 7Click "Clear" to reset both panels and start fresh.
Use Cases
- →Preview a README or documentation file before pushing it to a GitHub repository
- →Convert a Markdown blog post to HTML for pasting into a CMS or static site generator
- →Learn Markdown syntax interactively by writing and seeing the live output simultaneously
- →Export a Markdown document to HTML for use in an email campaign template
- →Verify table and code block syntax before adding documentation to a knowledge base
- →Convert meeting notes or technical specs from Markdown to HTML for browser viewing
- →Draft a post and watch the word count and reading time while you write, before it goes near a CMS
- →Build a GFM table without counting pipes by hand — insert the skeleton from the toolbar and fill it in
Tips
- ✓Use triple backticks followed by a language name (```javascript) for syntax-highlighted code blocks
- ✓GitHub Flavored Markdown tables use pipe (|) syntax — the live preview shows exactly how they render
- ✓The exported HTML includes inline styles — it displays correctly without external CSS
- ✓Use task lists (- [x] Done item) for Markdown checklists that render as checkboxes
- ✓Escape special Markdown characters with a backslash — e.g., \* for a literal asterisk
- ✓Switch the output to "HTML" to check the generated markup before pasting it into a CMS
- ✓The editor counts words, characters and reading time as you type, at the usual 200 words per minute
- ✓Everything rendered in the preview is sanitised with DOMPurify first, so pasting Markdown from an untrusted source cannot execute anything
- ✓Footnotes ([^1]) are not supported — use a linked list at the end of the document instead
Frequently Asked Questions
Markdown is a lightweight markup language that lets you add formatting to plain text using simple symbols. **Bold**, *italic*, # headings, - lists, and [links](url) are all written as plain characters.
This converter supports GitHub Flavored Markdown (GFM): headings (# through ######), bold, italic, strikethrough, inline code, fenced code blocks, blockquotes, ordered and unordered lists, task lists, tables, horizontal rules, links, and images. Footnote syntax ([^1]) is not supported and will appear as plain text.
It downloads a complete, self-contained HTML file with embedded CSS styling. You can open the file directly in any browser or embed the body content into your existing project.
Yes. All generated HTML is sanitized with DOMPurify before rendering, which removes any malicious scripts or dangerous attributes.
Yes. Tag a fenced code block with a language (```javascript) and the preview colours it — JavaScript, TypeScript, JSX, TSX, JSON, Python, Bash, SQL, YAML, HTML and CSS are recognised. The HTML you copy or download stays clean: the language is preserved as class="language-javascript" so your own site's highlighter can style it.
Each toolbar button inserts or wraps Markdown syntax. If you have text selected, the button wraps it — for example, selecting "hello" and clicking Bold produces **hello**.
Absolutely. Write your content in the Markdown editor, then click Download .html for a ready-to-use file or Copy HTML to paste the body content into your CMS or documentation system.
