Markdown to HTML converter for drafts, README excerpts, and documentation. Paste Markdown, review the HTML source, and copy it into the destination editor.
The Markdown to HTML Converter turns Markdown into HTML source for a publishing system or HTML editor. Paste a draft, README excerpt, or documentation snippet and review the generated tags. Conversion uses marked.
Markdown headings such as # and ##, emphasis such as **bold** and *italic*, and lists become HTML elements. The output box shows source text, not a styled preview of your destination page.
Use the converter when the destination accepts HTML but not Markdown. A CMS, email template, or application may apply its own formatting rules, so inspect the result after pasting.
The parser is marked. Check any extensions against your destination renderer rather than assuming every Markdown implementation behaves identically.
Headings from # through ###### become <h1> through <h6>. Emphasis using *text* or _text_ becomes <em>; **text** or __text__ becomes <strong>.
Inline code becomes <code>. Fenced code blocks become <pre><code>. List markers -, *, and + create <ul>; ordered items beginning with 1. create <ol>.
Links such as [text](url) become <a>, and images such as  become <img>. A > prefix creates <blockquote>. Horizontal-rule markers ---, ***, or ___ create <hr>. Supported pipe-table syntax becomes <table>.
Preview the result in the destination, or save a local .html file for inspection. The destination's stylesheet determines how the elements look.
For headings, compare ATX syntax such as ## Heading with Setext syntax such as Heading\n---. Keep indentation consistent, especially in nested lists and code blocks.
Check escaping around <, >, and &. Their escaped forms are <, >, and &. Inspect whether the destination expects literal text or an HTML element to avoid double escaping.
The marked parser can emit HTML from embedded markup; conversion is not sanitization. Sanitize untrusted output with an appropriate HTML sanitizer, such as DOMPurify, before injecting it into an application page.
Using marked does not establish a privacy guarantee for the page. Follow your organization's handling requirements before entering confidential drafts or internal documentation.
