Why it Matters

Markdown is the universal write-once-publish-everywhere format. Converting to HTML is the most common transform — needed for emails, blog imports, CMS migrations, and quick web previews. Using the unified.js stack guarantees output consistent with most static-site generators.

Frequently Asked Questions

What does GFM add over plain Markdown?
GitHub-Flavoured Markdown adds: pipe tables, fenced code blocks with language, task lists ([ ] / [x]), strikethrough (~~text~~), and autolinks for URLs without explicit syntax.
Is it safe to enable 'Allow raw HTML'?
Only with trusted input. Raw HTML lets the input inject `<script>` tags. We default it off; enable only when converting your own content.
Why doesn't it support custom React components like MDX?
MDX is a superset that needs a build step to compile JSX. This tool is the pure Markdown → HTML subset, runnable in the browser without a build.
