FAQ

Does this tool upload my Markdown or HTML?

No. Conversion runs in your browser; nothing is sent to a server.

What Markdown features are supported?

Headings, paragraphs, bold/italic/strike, links, inline code, fenced code blocks, blockquotes, lists, and horizontal rules.

Can I convert HTML back to Markdown?

Yes—switch to HTML → Markdown, paste HTML, then convert.

Is the HTML output safe to preview?

The Markdown → HTML preview is generated from escaped text plus a limited set of tags, and link URLs are sanitized (e.g., javascript: becomes #).

Why does my converted Markdown/HTML look different than GitHub?

GitHub supports extra Markdown extensions; this tool targets a lightweight, common subset for fast conversion.

Can I generate a full HTML page (doctype, head, body)?

Yes—enable Wrap as full HTML document to wrap the generated HTML in a minimal page template.

What does “Compact output” do?

It removes extra whitespace and newlines between tags to keep the output shorter.
