Frequently asked questions
Does this tool upload my Markdown? No. All conversion happens locally in your browser. Your content never leaves your device.
Does it support nested formatting? Yes. Inline styles like bold and italic can be combined, and inline code works inside other elements where the syntax allows.
How are code blocks handled? Triple-backtick fenced blocks become <pre><code> elements with preserved whitespace and newlines.
Is the HTML output safe to use? The converter escapes HTML first, then applies Markdown rules, so raw HTML in your input is treated as text rather than executed.
