How to Use the Markdown to HTML Converter
 What is Markdown?
Markdown is a lightweight markup language created by John Gruber in 2004. It uses plain-text formatting syntax that can be converted to HTML. It's widely used for README files, blog posts, documentation, and messaging — making it easy to write formatted content without dealing with HTML tags.
 Supported Markdown syntax:
  • Headings: # H1 through ###### H6
  • Bold: **text** or __text__
  • Italic: *text* or _text_
  • Bold + Italic: ***text***
  • Strikethrough: ~~text~~
  • Links: [text](url)
  • Images: ![alt](url)
  • Inline code: `code`
  • Code blocks: ``` code ```
  • Unordered lists: - item, * item, + item
  • Ordered lists: 1. item
  • Blockquotes: > quote
  • Horizontal rules: ---, ***
  • Tables: pipe-separated with header divider
 Features:
  • Markdown → HTML: Converts all common Markdown syntax to clean, semantic HTML.
  • HTML → Markdown: Converts HTML back to readable Markdown — great for reverse-engineering content.
  • Live preview: Results update instantly as you type.
  • Code block support: Preserves code blocks with optional language hints.
  • Table support: Full Markdown table parsing with proper HTML table output.
  • 100% client-side: Your content never leaves your browser — completely private.
