What is Markdown to HTML?

Markdown to HTML converts Markdown text to clean, ready-to-use HTML in real time, supporting GitHub Flavored Markdown with tables, task lists, and syntax-highlighted code blocks.

The output is an HTML fragment — no <html>, <head>, or <body> wrapper. Paste it directly into templates, CMS fields, or email builders.

Supported Markdown Features

Text Formatting

Headings (H1–H6), bold, italic, strikethrough, inline code, and blockquotes.

Lists & Tables

Ordered lists, unordered lists, nested lists, task lists (- [ ] checkbox), and GFM tables.

Code Blocks

Fenced code blocks with language hints are syntax-highlighted. Inline code is styled with monospace.

Common Markdown Syntax Reference

Markdown	Output
`# Heading`	`<h1>Heading</h1>`
`bold`	`<strong>bold</strong>`
`italic`	`<em>italic</em>`
`code`	`<code>code</code>`
`[link](url)`	`<a href="url">link</a>`
`![alt](url)`	`<img alt="alt" src="url">`

Tips & Common Mistakes

Tables require the header row. GFM tables need a header row and a separator row of dashes. If your table doesn’t render, check that the | --- | separator is present below the header.

Blank lines matter. In Markdown, a blank line separates paragraphs. Text on consecutive lines without a blank line between them is combined into one <p> element.

Frequently Asked Questions

What Markdown syntax is supported?

GitHub Flavored Markdown (GFM) — headings, bold, italic, strikethrough, blockquotes, ordered and unordered lists, task lists, tables, code blocks with language hints, and inline code.

What does 'fenced code block' mean?

Three backticks followed by a language name: ```javascript. This tells the converter to syntax-highlight the block as JavaScript code.

Can I use the HTML output in a CMS?

Yes. The output is a clean HTML fragment with no surrounding boilerplate (no <html>, <head>, <body>) — paste directly into a CMS rich text field or HTML template.

Does it sanitize the output?

Script tags and dangerous HTML attributes are stripped from the output for safety. Standard HTML elements are preserved.
