Convert MARKDOWN to XHTML Online
No official standard for advanced features; tables, footnotes, and math vary across parsers (CommonMark vs GFM vs MDX). Converting to XHTML gives you a key advantage: xml-strict syntax ensures documents are well-formed and machine-parseable, eliminating the ambiguity of loose html. XHTML is best for creating strictly validated web documents that conform to xml parsing rules.

expand_more
MARKDOWN (Markdown Text) is best for writing documentation and technical content with lightweight syntax that stays readable as plain text. XHTML (Extensible HyperText Markup Language) is best for creating strictly validated web documents that conform to xml parsing rules. Key tradeoff: MARKDOWN's advantage is human-readable source that doubles as formatted output — no rendering needed to understand the structure, while XHTML's advantage is xml-strict syntax ensures documents are well-formed and machine-parseable, eliminating the ambiguity of loose html.
