Markdown is a lightweight plain-text formatting syntax that converts into HTML — used for READMEs, documentation, chat messages, and static site content. This tool renders a live preview as you type, so you can check how headings, lists, links, and code blocks will actually look before publishing.
Rendering follows CommonMark plus common GitHub-Flavored Markdown extensions (tables, fenced code blocks, strikethrough), and the resulting HTML is sanitized before display, so pasting untrusted Markdown never executes a script in your browser.
Everything runs client-side using marked and DOMPurify — nothing you type is sent to a server.
Which Markdown flavor is supported?
This tool uses the marked library, which follows the CommonMark spec plus common GitHub-Flavored Markdown extensions like tables and fenced code blocks.
Is the rendered HTML safe from malicious input?
Yes — the output is sanitized with DOMPurify before being displayed, stripping scripts and other dangerous markup, so pasting untrusted Markdown won't execute code in your browser.
Does this support raw HTML inside Markdown?
Raw HTML tags are parsed, but the sanitizer removes anything unsafe (like <script> or inline event handlers) before rendering, so only safe formatting tags come through.
