About the Markdown Previewer
The Markdown Previewer turns Markdown text into a formatted, rendered view while you type, so you can see exactly how headings, lists, links, code blocks, and emphasis will look before you publish them. It is a small, focused editor for anyone who writes README files, documentation, GitHub issues, blog posts, or notes in Markdown and wants instant feedback.
Alongside the live preview, the tool generates the underlying HTML that your Markdown produces. This is useful when you need to paste real HTML into a content system that does not understand Markdown, or when you are debugging why a particular block renders the way it does. You can copy the HTML output with a single click and drop it straight into your page.
The preview follows the common Markdown conventions you already know: pound signs for headings, dashes or numbers for lists, backticks for inline code, fenced blocks for longer snippets, and square brackets with parentheses for links. Start from the sample text in the editor, clear it, and replace it with your own to see your document take shape line by line.
Everything happens in your browser. Your Markdown is parsed and rendered locally using JavaScript, and nothing you type is uploaded to a server or stored anywhere. Close the tab and the text is gone, which makes this a safe place to draft private notes or unpublished content.

Frequently asked questions
How do I convert Markdown to HTML?
Paste or type your Markdown into the editor on the left. The HTML output panel updates instantly with the generated markup, and you can copy it with the copy button to use anywhere that accepts raw HTML.
Which Markdown features are supported?
Standard Markdown is supported: headings, bold and italic text, ordered and unordered lists, links, images, inline code, fenced code blocks, blockquotes, and horizontal rules. These cover the syntax used by most documentation and README files.
Is my Markdown uploaded or stored anywhere?
No. The previewer runs entirely in your browser and parses the text locally. Nothing is sent to a server, saved to a database, or logged. When you close or refresh the tab, your text is gone.
Why does my preview look different from GitHub?
GitHub adds its own styling and some extra syntax such as task lists and tables through its flavored Markdown. This tool renders standard Markdown, so spacing and a few advanced features may differ slightly, but the core structure will match.
Can I copy the rendered text instead of the HTML?
The copy button provides the generated HTML, which you can paste into HTML-aware editors. To reuse the source itself, simply copy the text directly from the input editor on the left.
