What is Markdown?
Created by John Gruber in 2004, Markdown is a lightweight markup language designed to be easy to read and write in plain text, while converting cleanly to HTML for the web.
Instead of writing <strong>bold</strong>, you simply write **bold**. This makes raw documents readable even without rendering.
Why Use This Converter?
Many tools support Markdown input, but few offer clean HTML export or the reverse conversion. Our tool excels at both:
- For Writers: Write in simple Markdown, export to HTML for WordPress/Medium.
- For Developers: Convert rich documentation to Markdown for version control.
- For Students: Clean up messy copy-pasted HTML from research sources.

Markdown is a lightweight markup language created by John Gruber in 2004. It uses plain text formatting syntax that's easy to read and write, and converts cleanly to HTML. It's widely used in README files, documentation, blogs, and forums like Reddit and GitHub.
How does Markdown to HTML conversion work?
Our tool uses the 'marked' JavaScript library to parse Markdown syntax and generate corresponding HTML elements. For example, # Heading becomes
Heading
, and bold becomes bold. The conversion follows CommonMark and GitHub-Flavored Markdown specifications.Can I convert HTML back to Markdown?
Yes! Switch to 'To Markdown' mode and paste your HTML. We use the Turndown library to intelligently strip HTML tags and convert them back into clean Markdown syntax. This is perfect for importing content from websites or rich text editors.
What Markdown syntax is supported?
We support standard Markdown (headings, bold, italic, links, images, lists) plus GitHub-Flavored Markdown extensions including tables, task lists, strikethrough, and fenced code blocks with syntax highlighting hints.
Is my content private and secure?
Absolutely. All conversion happens 100% in your browser using JavaScript. No text is ever uploaded to our servers, ensuring complete privacy for your documents, notes, or code.
Can I use this for README files?
Yes! This tool is perfect for GitHub README files. Write your documentation in Markdown, preview how it will look, then copy the Markdown back to your repository. Or convert existing HTML documentation to Markdown format.
What is the 'Live Preview' feature?
When converting Markdown to HTML, a styled preview panel appears below showing exactly how your HTML will render in a browser. This helps you catch formatting issues before publishing.
How do I create tables in Markdown?
Use pipe characters | to separate columns and hyphens --- for the header row. Example: | Header 1 | Header 2 | followed by | --- | --- | and then | Cell 1 | Cell 2 |. Our tool will convert this to a proper HTML table.
Can I paste from Microsoft Word or Google Docs?
When you paste from Word/Docs, it often includes HTML formatting. Switch to 'To Markdown' mode to clean it up and convert the rich text to simple, portable Markdown syntax that works everywhere.
Is there a file size limit?
No hard limit, but we recommend keeping documents under 1MB for optimal browser performance. The tool handles typical documentation and blog posts instantly.
What's the difference between Markdown and HTML?
Markdown is human-readable plain text with simple syntax (e.g., bold), while HTML uses verbose tags (e.g., bold). Markdown is easier to write and edit, but HTML offers more precise control over styling and structure.
Can I customize the HTML output?
The tool generates clean, semantic HTML following web standards. If you need custom classes or IDs, you can manually edit the HTML output before copying or downloading it.
