关于Markdown to HTML

The Markdown to HTML Converter transforms Markdown-formatted text into clean, standards-compliant HTML in real time. Markdown is a lightweight markup language created by John Gruber in 2004 that lets writers format text using simple punctuation — # for headings, ** for bold, - for lists — rather than verbose HTML tags. This tool converts all major Markdown elements: headings (H1–H6), bold, italic, strikethrough, inline code, fenced code blocks with language classes, blockquotes, ordered and unordered lists, tables, horizontal rules, images, and links. A live split-pane view lets you see the rendered HTML preview alongside your Markdown input as you type. You can copy the raw HTML output or download a complete, self-contained HTML file with inline CSS styling ready to open in any browser. All conversion runs entirely in your browser — no data is ever sent to a server.

如何使用Markdown to HTML

  1. Type or paste your Markdown text into the left panel. Click "Load Sample" to see an example with all supported syntax.
  2. Watch the right panel update in real time — switch between the "HTML" tab to see raw HTML output and the "Preview" tab to see the rendered result.
  3. Use standard Markdown syntax: # for headings, **bold**, *italic*, `code`, ``` for code blocks, - for lists, | for tables, and > for blockquotes.
  4. Review the HTML tab to verify the generated markup matches your needs.
  5. Click "Copy" to copy the HTML fragment to your clipboard, or click "Download" to save a complete, styled HTML file.
  6. Paste the HTML into your website, blog CMS, email template, or any other HTML-aware application.

常见问题

What Markdown syntax is supported?

The converter supports headings (H1–H6), bold, italic, strikethrough, inline code, fenced code blocks with language class attributes, blockquotes, unordered and ordered lists, GFM-style pipe tables, horizontal rules (---), images, and hyperlinks. Nested lists are not yet supported.

What is the difference between copying the HTML and downloading it?

Copying gives you the HTML fragment — just the content tags without a surrounding document structure. Downloading gives you a complete standalone HTML file with a DOCTYPE, head section, meta tags, and inline CSS styling for headings, code blocks, tables, and blockquotes.

Is the conversion done on a server?

No. All conversion happens entirely in your browser using a built-in JavaScript parser. Your text never leaves your device, making it safe to use with private or sensitive content.

Can I use the output in a CMS like WordPress or Ghost?

Yes. Copy the HTML fragment and paste it into your CMS's HTML editor or code block. The output uses standard HTML5 tags that are compatible with virtually all content management systems.

Does it support GitHub Flavored Markdown (GFM) tables?

Yes. Pipe tables (| Col1 | Col2 |) are fully supported, including the separator row with alignment colons. The output is a proper <table> element with <thead> and <tbody> sections.

Why are code blocks given a language class?

When you write a fenced code block with a language hint (e.g., ```javascript), the converter adds a class="language-javascript" attribute to the <code> element. This allows syntax highlighting libraries like Prism.js or highlight.js to colorize the code automatically.
