Is the HTML safe?

Rendered output is sanitized — script tags, inline event handlers and javascript: URLs are stripped before display.

Is my data uploaded anywhere?

No. This tool runs entirely as JavaScript in your browser — your input never leaves your device and nothing is logged.

Type or paste Markdown on the left.

Supports headings, lists, links, tables and code blocks.
