About Markdown Converter
Markdown Converter is a free online tool that transforms Markdown syntax into clean, valid HTML. Markdown is a lightweight markup language created by John Gruber in 2004, designed to be easy to read and write while converting seamlessly to HTML. It's become the standard for documentation, README files, and content creation across platforms like GitHub, GitLab, and many static site generators.
What is Markdown?
Markdown is a plain text formatting syntax that allows you to write using an easy-to-read, easy-to-write format that converts to structurally valid HTML. It's widely used for documentation, README files, blog posts, and content management systems. Unlike WYSIWYG editors, Markdown keeps your content separate from formatting, making it ideal for version control and collaboration.

- Headers: # H1, ## H2, ### H3, etc. (up to 6 levels)
- Emphasis: **bold**, *italic*, ~~strikethrough~~, ***bold italic***
- Lists: Ordered (1., 2., 3.) and unordered (-, *, +)
- Links: [text](url) and [text](url "title") with optional titles
- Images:  with alt text support
- Code: Inline `code` and fenced code blocks with language hints
- Blockquotes: > quoted text (supports nesting)
- Tables: | Column | Column | with alignment (:-:)

- Definition lists: Term : Definition

This tool converts Markdown to HTML only. For HTML to Markdown conversion, you would need a different tool like Turndown.js, Pandoc, or similar libraries designed for that purpose. HTML to Markdown conversion is more complex and may not always produce perfect results due to HTML's flexibility and Markdown's limitations.
