Markdown to HTML Converter
Convert your Markdown to clean, standards-compliant HTML instantly.
About This Tool
The Markdown to HTML Converter is a free, browser-based tool that transforms Markdown text into clean, standards-compliant HTML. Whether you are writing documentation, preparing content for a CMS, building email templates, or converting README files for publication, this tool produces well-structured HTML you can use right away.
All conversion happens entirely in your browser using a custom parser built without any external libraries. Your content never leaves your machine — there are no server requests, no logging, and no third-party tracking. This makes it safe for proprietary documentation, internal wikis, and sensitive content.
The converter supports GitHub Flavored Markdown (GFM), which includes headings (H1 through H6), bold, italic, and strikethrough text, hyperlinks, images with alt text and titles, unordered and ordered lists, task lists with checkboxes, fenced code blocks with optional language annotations, blockquotes, horizontal rules, and tables with column alignment. Inline formatting such as inline code, combined bold-italic, and line breaks are also supported.
The two-column interface lets you type or paste Markdown on the left and see the HTML output on the right in real time. You can switch between a raw HTML code view and a rendered preview to verify the output visually. A single click copies the generated HTML to your clipboard, ready to paste into your project. The tool is designed for speed: there is no build step, no compile delay, and no round-trip to a server.
How to Use
- Type or paste your Markdown into the Markdown Input panel on the left.
- The HTML output updates automatically in real time on the right side.
- Use the Raw HTML tab to see the generated HTML code, or the Preview tab to see the rendered result.
- Click Copy HTML (or press Ctrl+Shift+C) to copy the HTML to your clipboard.
- Click Sample to load example Markdown that demonstrates all supported features.
- Click Clear to reset both panels and start fresh.

FAQ
Is my data safe when using this tool?
Yes. All Markdown parsing and HTML generation runs entirely in your browser using client-side JavaScript. No data is transmitted to any server, making it safe for confidential and proprietary content.
Which Markdown features are supported?
The converter supports GitHub Flavored Markdown (GFM) including headings, bold, italic, strikethrough, links, images, unordered and ordered lists, task lists, fenced code blocks with language hints, blockquotes, horizontal rules, tables with alignment, and inline code.
Does it use any external libraries?
No. The Markdown parser is implemented from scratch without relying on libraries like marked, remark, or markdown-it. This keeps the tool lightweight with zero additional dependencies.
Can I see a preview of the rendered HTML?
Yes. Switch to the Preview tab in the output panel to see the HTML rendered visually. The Raw HTML tab shows the underlying code you can copy and paste into your projects.
How do I copy the generated HTML?
Click the Copy HTML button or use the keyboard shortcut Ctrl+Shift+C. The button shows a checkmark confirmation when the copy succeeds.
Does it handle large Markdown documents?
The converter processes input in real time and handles documents of typical sizes (up to several thousand lines) without issues. Since everything runs locally, performance depends on your device but is generally instant for most documents.
What is the difference between this tool and the Markdown Preview tool?
The Markdown Preview tool focuses on writing and previewing Markdown visually. This Markdown to HTML converter is designed to produce clean HTML source code you can copy and use in web pages, emails, CMS platforms, or any context that requires raw HTML output.
