Convert Markdown text to clean HTML with support for tables, code blocks, and lists.
Paste Markdown and this tool converts it to clean, ready-to-paste HTML — headings become <h1>-<h6>, **bold** becomes <strong>, lists become <ul>/<ol>, and fenced code blocks become <pre><code>. It supports common GitHub-Flavored Markdown extensions like tables, task lists, and strikethrough, and shows both the rendered preview and the raw HTML. The conversion happens in your browser, so your draft content is never uploaded.

What is Markdown to HTML?
A Markdown-to-HTML converter transforms Markdown — the lightweight plain-text formatting syntax created by John Gruber — into the HTML markup browsers render. Markdown lets you write structured documents (headings, lists, links, code) using simple characters like # and *, which are then compiled to semantic HTML tags. This tool performs that compilation, so you can author in comfortable Markdown and get standards-compliant HTML for a CMS, email, static site, or documentation page.
How to use Markdown to HTML
1
Paste your Markdown
Drop in your Markdown source — a README, a blog draft, release notes, anything using #, *, -, [links](), and ```code``` fences.
2
Get the HTML output
The tool parses the Markdown and produces semantic HTML: proper heading levels, paragraph tags, list structures, links, images, and code blocks.
3
Preview the rendering
Check the rendered preview to confirm the structure matches your intent before you use the markup — a mismatched heading level or broken list shows up immediately.
4
Copy the HTML
Copy the generated HTML and paste it into your CMS, email template, static-site source, or wherever you need raw markup instead of Markdown.
Try it when you need to…
Try it when your CMS or email tool only accepts HTML but you've written your content in Markdown
Try it when you need to embed a formatted README on a webpage as raw HTML
Try it when you want to check exactly what HTML tags your Markdown compiles to
Use cases
Converting a GitHub README written in Markdown into HTML for a project website

Producing accessible, semantic markup from Markdown for a blog post
Key features
✓Converts headings, emphasis, lists, links, images, and blockquotes to semantic HTML
✓Supports GitHub-Flavored Markdown: tables, task lists, strikethrough, and fenced code
✓Live rendered preview alongside the raw HTML output
✓Preserves fenced code blocks as <pre><code> for syntax highlighting
✓Runs entirely client-side so drafts stay private
Tips & best practices
There is no single Markdown standard — flavours differ. CommonMark is the strict spec, GitHub-Flavored Markdown (GFM) adds tables and task lists, and other renderers add their own extras. If a table or ~~strikethrough~~ doesn't convert, the target renderer may not support that GFM extension.
Markdown lets you drop raw HTML inline, so if you need something Markdown can't express (a <details> element, a styled span), just write the HTML directly in your source and most parsers will pass it through untouched.
Blank lines matter. Markdown separates paragraphs by blank lines, and a list or code fence that isn't preceded by a blank line can be swallowed into the previous paragraph. When output looks wrong, check your spacing first.
Watch out for characters that Markdown treats as syntax — underscores in file_names, asterisks, and backticks. Escape them with a backslash (\_) if you want them shown literally rather than interpreted as emphasis or code.
Frequently asked questions
Markdown is a plain-text formatting syntax that uses simple characters — # for headings, * for emphasis, - for lists — to describe document structure. It's easy to write and read, but browsers only render HTML, so to publish Markdown on the web you compile it to HTML tags like <h1>, <strong>, and <ul>. This tool does that compilation for you.
Yes. Beyond the core CommonMark syntax it handles GitHub-Flavored Markdown extensions including tables (with pipe | delimiters), task list checkboxes, strikethrough with ~~text~~, and fenced code blocks with language hints. These are the extensions most people mean when they say "Markdown" today.
Yes. Markdown by design lets you mix in raw HTML, so if you need an element the syntax can't produce — say a <details>/<summary> disclosure or a table with colspan — you can write that HTML directly in the source and the parser will pass it through to the output unchanged.
Indented (4-space) and fenced (triple-backtick) code blocks are converted to <pre><code> elements, which preserve whitespace and disable further Markdown interpretation inside them. If you add a language after the opening fence (```js), that language is emitted as a class on the code element so a syntax highlighter can style it later.
Tables are a GFM extension, not part of core Markdown, so they require the pipe-and-dash syntax and a header separator row (like |---|---|). Common mistakes are omitting that separator row, or missing the blank line before the table. Check those two things and the table should render.
Yes. The Markdown is parsed in your browser with JavaScript and never sent to a server, so drafts, internal docs, and unreleased notes stay on your machine. That also means it keeps working if your connection drops after the page loads.
CommonMark is a strict, unambiguous specification of core Markdown that resolves the edge cases the original 2004 spec left undefined. GitHub-Flavored Markdown is a superset that adds tables, task lists, strikethrough, and automatic URL linking on top of CommonMark. Content that uses only core syntax converts identically under both; content using GFM features needs a GFM-aware parser.
