Markdown to HTML Converter(MD to HTML) — Free Online Converter
How to use it
Three steps. No installation, no signup.
Paste your Markdown on the left
Type it, paste it, or drag a .md file into the box. The converter reads it instantly.
The HTML appears on the right
You'll see the formatted HTML code in real time. A live preview tab shows what it'll look like in a browser.
Click "Copy HTML"
Now paste the HTML wherever you need it — your blog, your email, your website, your Notion page. That's it.
What you can do with this converter
This one converter handles every common Markdown-to-HTML job — READMEs, blog posts, AI-generated text, emails, and static-site content. Pick the section that matches what you're doing.
Convert a README.md file to HTML
Drop your README.md into the editor and download the result as a standalone HTML page.
The output uses GitHub's own styling, so it looks the same as your README on GitHub but works as a regular webpage.
Turn AI-generated Markdown into something you can publish
ChatGPT, Claude, and Gemini all write in Markdown by default.
Paste their output here, get publish-ready HTML for your blog, your CMS, or your email.
Write a blog post in Markdown, then publish it anywhere
Most blogging tools accept HTML in a "raw HTML" or "code" block.
Write your post in Markdown (faster, cleaner, no formatting toolbar fights), convert it here, and paste into WordPress, Ghost, Substack, or Medium.
Format an email with Markdown
Turn on "Inline CSS" before copying.
It bakes the styling into each tag so Gmail, Outlook, and Apple Mail render it correctly. Then paste the HTML into the source view of your email composer.
Convert Markdown to clean HTML for static sites
If you're building with Hugo, Jekyll, Next.js, Astro, or Gatsby, the build process already does this conversion automatically.
Use this tool to preview exactly what your site generator will produce, or to convert one-off content for migration.
Need to go the other way?
Switch to the HTML → Markdown tab to convert HTML back into Markdown.
Useful for cleaning up content before pasting into ChatGPT, exporting blog posts to Markdown, or migrating to a Markdown-based notes app like Obsidian or Notion.
Need to add a table to Squarespace?
Switch to the Table for Squarespace tab.
Squarespace's Markdown block doesn't render tables, but there's a one-step workaround that does.
What kind of Markdown does this support?
Everything in CommonMark plus the GitHub-Flavored Markdown extensions — the same things GitHub renders in a README.
In plain terms, you can use:
- Headings (
#,##,###) - Bold, italic,
strikethrough,inline code - Bulleted and numbered lists, including nested ones
- Checkbox lists (
- [ ]and- [x]) - Tables with column alignment
- Code blocks with syntax highlighting for 200+ languages
- Quotes (the
>symbol) - Links and images
- Footnotes
- Math equations (LaTeX style:
$E=mc^2$) - Mermaid diagrams (flowcharts, sequence, gantt)
- GitHub-style alerts (
[!NOTE],[!WARNING], ...) - Inline HTML, if you need it
If you've ever written a GitHub README, you already know what works.
Your text never leaves your computer
The conversion happens entirely in your browser. Nothing is uploaded, nothing is logged, nothing is stored. There's no account, no email, no cookies for the conversion itself.
If you're skeptical (you should be — most "free online" tools quietly send your text to a server), open your browser's developer tools and watch the Network tab while you convert. You'll see zero requests fire. The converter is a small JavaScript file your browser downloads once and then runs locally — even offline, if you install it as an app.
Frequently asked questions
Yes — md is the file extension for Markdown. A .md file contains Markdown text. "Convert md to html" and "convert markdown to html" mean the same thing.
Markdown is a simple way to write formatted text using plain symbols (like # for a heading or ** for bold). HTML is the code browsers use to display that formatting. This converter is the bridge between the two.

Click the "HTML → Markdown" tab at the top. Paste your HTML, get clean Markdown back.
No. It runs in your browser. You can also "install" it as an app from your browser menu so it works offline.
Yes. The conversion happens in your browser — nothing is uploaded. Open your browser's developer tools → Network tab while you convert. You'll see zero requests. Your text never goes to a server.
Yes — full support for everything GitHub renders, including tables, task lists, strikethrough, fenced code blocks with language detection, and footnotes.
The most common cause is missing blank lines. Lists, code blocks, and quotes need an empty line above and below them. The second most common: nested lists need to be indented with 2 or 4 spaces, not tabs.
Yes. Open the settings panel and either inline your CSS (best for email — bakes the styles into each tag) or wrap the output in a full HTML document with a <style> block.
Yes — drop multiple .md files into the editor and download them as a single zip.
No. The tool is free and we don't plan to change that.
Squarespace's Markdown block doesn't render tables, but its Code Block does render HTML. Use the Table for Squarespace tab on this site for a step-by-step guide and a one-click "Copy HTML for Squarespace" button.
