Markdown is converted to HTML using the marked.js library, which supports CommonMark and GitHub Flavored Markdown (GFM). GFM adds: fenced code blocks, tables, strikethrough (~~text~~), task lists (- [x]), and autolinks.
Headings use # prefix. Bold: **text**. Italic: *text*. Links: [label](url). Images: . Inline code: backtick. Block code: triple backtick with optional language name. Unordered lists use - or *.
The rendered HTML export wraps the converted content in a complete HTML document with basic styling. The exported file is self-contained and can be opened directly in any browser without requiring Markdown software.
Math equations (LaTeX) are not supported natively. Raw HTML embedded in Markdown is rendered by default. For complex documents with precise formatting, consider exporting to DOCX or PDF instead.
