• Converting Markdown notes into HTML for a pageTurn Markdown written in a notes app or README into HTML you can paste into a CMS or email template.
• Converting pasted HTML back into clean MarkdownPaste HTML copied from a webpage or rich-text editor and get a Markdown version for a README, wiki, or Markdown-based note.
• Checking how a piece of Markdown will render as HTMLSee the exact HTML tags a piece of Markdown produces, useful when debugging Markdown-rendering issues.

• Headings and emphasis"# Title" becomes "<h1>Title</h1>"; "**bold**" becomes "<strong>bold</strong>"; "*italic*" becomes "<em>italic</em>".
• A list"- one\n- two" becomes "<ul><li>one</li><li>two</li></ul>".
• A code block keeps its contents literalText inside a fenced code block (```...```) is never interpreted as Markdown formatting — asterisks, brackets, and other Markdown syntax inside a code block are shown exactly as typed.

Headings (# through ######), bold (**text** or __text__), italic (*text* or _text_), inline code (`code`), fenced code blocks (```code```), links ([text](url)), unordered lists (- or * items), ordered lists (1. items), blockquotes (> text), and paragraphs. This is a common, practical subset — not the full CommonMark or HTML5 specification — so unusual constructs like tables, nested lists, footnotes, or raw HTML embedded inside Markdown are not guaranteed to convert correctly.

This tool always shows the converted output as plain text for you to copy, rather than rendering it as live HTML on the page. Rendering arbitrary generated HTML directly would create a cross-site-scripting (XSS) risk if the input contained something like a script tag — showing the result as text avoids that risk entirely, while still giving you the exact HTML string you need.

When converting Markdown to HTML, any text that looks like an HTML tag (for example, literal angle brackets in your Markdown) is escaped into safe HTML entities in the output, rather than being passed through as real markup — so pasting the result elsewhere never accidentally introduces executable code from your original Markdown text.

Does this support Markdown tables?

No — this converter covers a common subset of Markdown (headings, emphasis, links, lists, code, blockquotes) and does not include tables, footnotes, or other extended syntax.

Why is the HTML output not rendered as a live preview?

Showing generated HTML as live, rendered markup on the page would create a cross-site-scripting risk if the input contained something like a script tag. This tool always shows the result as plain text to copy, which avoids that risk while still giving you the exact HTML.

Will HTML-to-Markdown perfectly reverse Markdown-to-HTML?

For the supported subset (headings, bold, italic, code, links, lists, blockquotes) in simple, non-nested form, yes. More complex or unusual HTML structures may not convert back to identical Markdown.

Is my text saved?

No. Everything is calculated in your browser; nothing is sent to a server.
