The Complete Guide to Markdown to HTML Conversion

Markdown is the go-to plain-text format for READMEs, blog posts, documentation, and notes because it's easy to write and easy to read even before it's rendered. Our free Markdown to HTML Converter lets you write Markdown and instantly see the exact HTML it produces, side by side, directly in your browser.

Supported Markdown Syntax

Headers (# through ######), bold (**text** or __text__), italic (*text* or _text_), inline code, fenced code blocks (triple backtick), links, images, unordered lists (- or *), ordered lists (1.), blockquotes (>), and horizontal rules (---).

How We Keep the Preview Safe

This tool renders real HTML into the live preview so you see true formatted output — but before anything reaches the page, every raw text run is escaped and only a fixed, whitelisted set of tags (headers, paragraphs, bold, italic, code, links, images, lists, blockquotes) is ever generated by our parser. If you paste markdown that contains a literal <script> tag, it shows up as visible text in the preview instead of executing.

Frequently Asked Questions

Is my markdown content sent to any server?

No. All parsing and rendering happens entirely in your browser using JavaScript. Your text never leaves your device.

Which Markdown syntax is supported?

Headers (# through ######), bold (**text** or __text__), italic (*text* or _text_), inline code, fenced code blocks, links, images, unordered and ordered lists, blockquotes, and horizontal rules.

Is it safe to paste markdown that contains raw HTML or script tags?

Yes. Any literal HTML you type (like <script> tags) is automatically escaped and shown as plain visible text in the preview instead of being executed — it can never run code in your browser.

Can I copy the generated HTML?

Yes, click "Copy HTML" to copy the raw generated HTML markup (not the rendered preview) straight to your clipboard, ready to paste into your own project.
