How It Works
Markdown is a lightweight markup language created by John Gruber in 2004 that uses plain text formatting syntax to create rich, structured text. Instead of writing verbose HTML tags, you use simple conventions like # Heading, **bold**, and - list item to express formatting intent.
This converter parses your Markdown syntax and generates the corresponding HTML elements. It processes the document in two passes: first identifying block-level structures (headings, code blocks, blockquotes, lists, tables, paragraphs), then applying inline formatting (bold, italic, links, images, code) within each block.
The tool follows the CommonMark specification and also supports several GitHub Flavored Markdown (GFM) extensions, including fenced code blocks with language hints, tables with column alignment, strikethrough text, and task list checkboxes.
