About Markdown to HTML

The Markdown to HTML Converter is a free browser-based tool that transforms Markdown text into clean, standards-compliant HTML in real time. It handles all common Markdown elements: headings (H1–H6), bold and italic text, strikethrough, inline code and fenced code blocks, blockquotes, unordered and ordered lists, images, links, and horizontal rules — making it a complete solution for most Markdown-to-HTML conversion needs.

This tool is widely used by developers, technical writers, bloggers, and content creators who write content in Markdown and need the raw HTML for embedding in web pages, CMS systems, email templates, or documentation sites. The split-pane interface lets you type on the left and instantly see both the rendered HTML preview and the raw HTML code on the right, toggled with a single button click.

The conversion engine is a custom regex-based Markdown parser written entirely in JavaScript. It processes the Markdown string in a defined order — code blocks first to avoid double-processing, then headers, formatting, links, lists, and finally paragraph wrapping. This client-side approach means conversion is instantaneous and no text is ever sent to a server.

Frequently Asked Questions

What Markdown syntax does this converter support?

The converter supports: headings (# through ######), bold (**text** or __text__), italic (*text* or _text_), bold+italic (***text***), strikethrough (~~text~~), inline code (`code`), fenced code blocks (```lang), blockquotes (> text), unordered lists (- or *), images (![alt](url)), links ([text](url)), and horizontal rules (---).

How do I switch between the HTML preview and the raw HTML code?

Click the "View Code" button in the top-right of the output panel to switch from the rendered preview to the raw HTML text. Click "Preview" to switch back. The Copy button always copies the raw HTML regardless of which view is active.

Can I use the generated HTML directly in a webpage?

Yes. The output is clean HTML using standard tags like <h1>, <p>, <ul>, <pre>, <code>, <blockquote>, and <a>. You can paste it directly into any HTML file or CMS editor. You may want to add a stylesheet to style the elements, as no inline styles are added.

Does this tool support ordered lists?

The converter transforms numbered list syntax (1. item) into <li> elements, but they are currently wrapped in <ul> rather than <ol>. For most display purposes this is sufficient, but if you need strict ordered list semantics, you may want to manually adjust the output.

Is there a size limit for the Markdown input?

There is no enforced size limit — you can paste as much Markdown as you like. Since all processing happens in the browser, performance depends on your device. For very large documents (hundreds of kilobytes), you may notice a brief processing delay.

Does the converter support tables or task lists?

The current implementation focuses on the most common Markdown elements and does not include GitHub Flavored Markdown extensions like tables, task lists, or footnotes. Use a full GFM parser like marked.js or remark if you need those features.

Is the Markdown to HTML Converter free?

Yes, it is completely free with no usage limits and no account required. It is part of liminfo.com's collection of free online developer tools.

Is my data safe when using this tool?

Absolutely. The conversion happens entirely within your web browser. No Markdown text or generated HTML is ever sent to a server, stored, or shared with anyone.
