How this tool works
The input is HTML-escaped first, then a small Markdown subset is transformed into headings, paragraphs, emphasis, inline code and unordered lists.
Example
Typing # Title, **bold text** and - list items produces a corresponding formatted preview without executing arbitrary HTML.
Common questions
Does this implement the full CommonMark specification?
No. It intentionally supports a practical subset rather than every Markdown extension.
Can pasted HTML execute?
No. Raw characters are escaped before Markdown transformations, reducing script-injection risk in the preview.
