How it works
What is Markdown?
Markdown is a lightweight markup language that uses plain text formatting syntax. It allows you to write using an easy-to-read, easy-to-write format that converts to structurally valid HTML. Markdown is widely used for documentation, README files, blog posts, and content management systems like GitHub and WordPress.
Basic Markdown Syntax
Our converter supports the most common Markdown elements:
- Headers: Use # for H1, ## for H2, ### for H3, and so on
- Bold: Wrap text in **double asterisks** or __double underscores__
- Italic: Wrap text in *single asterisks* or _single underscores_
- Lists: Use - or * for unordered lists, numbers for ordered lists
- Code: Inline code with `backticks`, code blocks with triple backticks
- Links: [link text](url) for hyperlinks
Examples
Example 1: Simple Header and Paragraph
Input: # Hello World
Output: <h1>Hello World</h1>
Example 2: Bold and Italic
Input: **Bold text** and *italic text*
Output: <p><strong>Bold text</strong> and <em>italic text</em></p>
Example 3: List and Link
Input: - Item 1\n- Item 2\n[Google](https://google.com)
Output: Unordered list with two items and a hyperlink.
Frequently Asked Questions
What is Markdown used for?
Markdown is used for documentation, README files, blog posts, forum posts, and any content that needs simple formatting. It is the default format on GitHub, Reddit, and many other platforms.
Does it support code blocks?
Yes. Use triple backticks for fenced code blocks. You can optionally specify a language for syntax highlighting in some contexts.
Is the conversion secure?
Yes. Our tool sanitizes all HTML output before displaying it, removing any potentially dangerous content. This prevents XSS (cross-site scripting) attacks.
Can I copy the HTML output?
Yes. Use the copy button to copy the raw HTML to your clipboard. You can then paste it into your website, CMS, or application.
Does it work with Unicode and special characters?
Yes. The converter handles UTF-8 Unicode, accented characters, and emojis correctly.
Is my content sent to a server?
No. All conversion happens locally in your browser. Your Markdown never leaves your device.
