Tips & tricks
- There's no live preview — you click Convert to HTML and get the raw HTML source as text, not a rendered view of the page.
- Only headings (h1–h3), bold, italic, inline code, links, and lists are supported — tables, task lists, strikethrough, blockquotes, images, and fenced code blocks are not converted at all and will appear as literal text wrapped in a paragraph tag.
- The output isn't sanitized — if you're rendering user-submitted Markdown on a live page, sanitize the HTML yourself first.

Frequently Asked Questions
What Markdown features does this converter support?
Headings (# ## ###, up to h3 only), **bold**, *italic*, `inline code`, [links](url), and unordered/ordered lists. That's the complete list.
Does this support GitHub Flavored Markdown (tables, task lists, strikethrough)?
No. Tables, task lists (- [ ]), strikethrough (~~text~~), fenced code blocks with syntax highlighting, blockquotes, images, and auto-linking URLs are all unsupported — none of that GFM syntax is parsed, it will pass through as literal text instead of being converted.
Does it show a live rendered HTML preview as I type?
No — there's no live preview panel. You click Convert to HTML and see the generated HTML source code as plain text in a box below; nothing renders visually on the page itself.
Can I include raw HTML in my Markdown?
The converter only recognizes the specific Markdown patterns it supports (headings, bold, italic, code, links, lists) — any other line, including raw HTML tags, is wrapped in a <p> tag and passed through as literal text rather than being specially parsed.
Is the output sanitized to prevent XSS attacks?
No — the converter does not sanitize output. If you're inserting user-generated Markdown into a live web page, sanitize the resulting HTML yourself before rendering it.
Can I use this to write blog posts in Markdown and publish as HTML?
For simple content using only the supported syntax (headings, bold, italic, links, lists), yes. For anything using tables, code blocks, or other GFM features, you'll need a full Markdown parser instead — most CMSes and static site generators already include one natively.
What formats does the Markdown to HTML support?
The Markdown to HTML converts between markdown, html, plain text, md. All conversions work in both directions — instantly, with no sign-up required.
Is my data safe when using the Markdown to HTML?
Completely safe. The Markdown to HTML processes everything locally in your browser. No input data, results, or usage information is ever transmitted to or stored on any server.
Is there a character or word limit for the Markdown to HTML?
The Markdown to HTML has no hard character limit — it processes text as large as your browser can handle, typically hundreds of thousands of characters. Very large inputs may be slower depending on your device.
Can the Markdown to HTML process text in other languages?
Yes. The Markdown to HTML handles all Unicode text correctly, including accented characters, CJK characters, Arabic, Cyrillic, and emoji. It works with any language that your browser renders, with no additional setup or language packs required.
