Preview rendered Markdown in real time. Paste Markdown on the left, see the sanitised HTML output on the right instantly. Runs entirely in your browser.
Frequently Asked Questions
Which Markdown spec does this follow?
This tool uses marked, which follows the CommonMark spec and supports GitHub Flavoured Markdown (GFM) — including tables, task lists, and fenced code blocks.
Is the rendered HTML safe?
Yes. The HTML output is sanitised with DOMPurify before display, so embedded scripts and unsafe attributes are stripped. The rendered preview cannot execute JavaScript.
Can I convert my data files to Markdown?
Yes — SmartQueryTools can convert CSV, JSON, Parquet, and other formats to Markdown tables using the file converter tools. Paste the output here to preview it.
Is my data private?
Yes — completely. Everything runs locally in your browser. Nothing is sent to any server, and nothing is retained after you close the tab.
