Questions and answers

What is Markdown to HTML Converter?

Markdown is a plain-text formatting syntax that converts to HTML for the web. This converter turns headings, lists, links, images, blockquotes, fenced code, GFM tables and strikethrough into HTML, with a live preview, highlighted HTML source and a download as a complete HTML page.

Does Markdown to HTML Converter support GitHub Flavored Markdown?

Partly. It converts GFM tables, strikethrough and fenced code blocks, adding a language-* class for the code's language. Task lists and bare-URL autolinks are not converted, and code blocks are not syntax-highlighted.
