Markdown ⇄ HTML Converter
A Markdown to HTML converter turns lightweight Markdown syntax into clean, ready-to-paste HTML — write # Heading and get <h1>Heading</h1>. It is the fastest way to draft content in readable plain text and publish it on the web without hand-writing tags. Type or paste Markdown into the editor, and the raw HTML appears instantly in the output box, ready to copy or download.
What gets converted
Markdown covers the constructs you use in real documents: headings, bold and italic, links, images, inline code, fenced code blocks, ordered and unordered lists, blockquotes, and horizontal rules. This tool covers core Markdown syntax — GitHub Flavored Markdown extensions such as tables, task lists, and strikethrough are not supported (see below).
Syntax quick reference
| You write | You get |
|---|---|
# Heading … ###### Heading | <h1> … <h6> |
**bold** | <strong>bold</strong> |
*italic* | <em>italic</em> |
[text](https://example.com) | <a href="...">text</a> |
`code` | <code>code</code> |
- item or 1. item | <ul> / <ol> with <li> |
> quote | <blockquote>quote</blockquote> |
Core Markdown only: no GFM extensions
This converter implements core Markdown, not GitHub Flavored Markdown — the tool's own FAQ confirms this scope. Three popular extensions do not work here: tables typed with pipes render as a literal paragraph of pipe characters, task lists (- [ ]) show the brackets as plain text instead of checkboxes, and ~~strikethrough~~ passes through unchanged. If your document needs a table, either write the <table> HTML by hand inside your Markdown (raw HTML passes through untouched) or use a GFM-capable converter.
How to use it
- Pick a direction: Markdown → HTML or HTML → Markdown.
- Type or paste your content into the editor — it converts as you type, and the raw HTML (or Markdown) appears in the output box.
- Copy the output or use the Download button to save it as a file.
What it expects
Any Markdown text using core syntax — headings, emphasis, links, images, code, lists, blockquotes, horizontal rules. Raw HTML mixed into the Markdown passes through unchanged, which is useful for embeds and for hand-written tables. For the reverse direction, paste HTML using common tags (headings, paragraphs, lists, links, images, bold/italic, code, blockquotes).
Works both ways: HTML → Markdown
The direction switch converts HTML back into Markdown — handy when you inherit a blob of HTML (from a CMS export or a copied web page) and want clean, editable source. The output uses the same core constructs: headings become # lines, <strong> becomes **, links become [text](url), and so on. Unusual or deeply nested HTML may lose some structure, so review the output before publishing.
A note on sanitization and XSS
This converter does not sanitize untrusted HTML: raw HTML in your Markdown passes straight through to the output. That is fine for your own content, but never render Markdown submitted by untrusted users as HTML without running it through a sanitizer (such as DOMPurify) first — otherwise a <script> tag in the Markdown becomes a script tag on your page.
Styling the output
The generated HTML is an unstyled fragment of semantic markup with no inline CSS — no <html>, <head>, or <body> wrapper — so it inherits your site's stylesheet when pasted into a page or CMS. That is exactly what you want for WordPress or an existing template, where a second set of document tags would break the page.
Limitations
This handles core Markdown and common HTML tags. Tables, footnotes, nested blockquotes, and unusual HTML structures may not convert perfectly — always review the output before publishing.
Frequently asked questions
- How do I convert Markdown to HTML?
- Paste your Markdown into the editor above and the tool converts it as you type — # Heading becomes <h1>Heading</h1>, **bold** becomes <strong>bold</strong>, and so on. The raw HTML appears in the output box; copy it or use the Download button to save it as a file. No sign-up or upload is needed; everything happens in your browser.
- What Markdown syntax is supported?
- Headings, bold, italic, links, images, inline code, fenced code blocks, blockquotes, unordered and ordered lists, and horizontal rules — the syntax used in most day-to-day writing.
- Does the converter support GitHub Flavored Markdown?
- No — this tool covers core Markdown syntax only. The most-used GFM extensions are not supported: a pipe table renders as a literal paragraph of pipe characters, - [ ] task lists show the brackets as plain text instead of checkboxes, and ~~strikethrough~~ passes through unchanged. For tables, write raw <table> HTML inside your Markdown (it passes through) or use a GFM-capable converter.
- Can I convert HTML back to Markdown?
- Yes — switch the direction control to HTML → Markdown and paste your HTML. Common tags convert cleanly: headings become # lines, <strong> becomes **, links become [text](url), and so on. Unusual or deeply nested HTML may lose some structure, so always review the output.
- Do I get a full HTML document or just a fragment?
- Just a fragment — the converted elements without <html>, <head>, or <body> wrappers. That is what you want when pasting into WordPress, a CMS, or an existing page. There is no full-document export; the Download button saves the fragment as-is.
- Is my content sent anywhere?
- No, the conversion happens entirely in your browser using JavaScript.
