Powered by marked.js — supports CommonMark + GitHub Flavored Markdown (tables, fenced code, autolinks). HTML→Markdown is a best-effort conversion of common tags.

?What is the Markdown ↔ HTML Converter?

The Markdown ↔ HTML Converter renders Markdown as HTML (or extracts Markdown from HTML) with a live preview pane. Powered by marked.js, which implements CommonMark plus GitHub Flavored Markdown extensions: tables, fenced code blocks, autolinks, strikethrough, task lists. Useful for blog post drafting, README generation, documentation conversion, email-template prep (many email clients accept HTML but not Markdown), and migrating notes between platforms (Notion, Obsidian, GitHub, GitLab, Slack).

The Formula

CommonMark: # h1, ## h2, **bold**, *italic*, [link](url), ![alt](img), `inline code`, ```fenced```, > quote, - list, 1. ordered, --- hr. GFM adds: | tables |, ~~strike~~, - [ ] tasks.

Practical Examples

Convert a GitHub README to HTML for embedding on a portfolio website.

2

4
