Markdown preview

Paste Markdown on the left; sanitized HTML preview updates as you type—ideal for README drafts.

Markdown parsing loads from a CDN; rendering runs locally. Preview links open in a new tab.

How Markdown preview works

The page parses Markdown with a lightweight library, then sanitizes HTML with DOMPurify to reduce script injection risk in your preview pane. It is still not a replacement for your CMS or static-site pipeline.

Privacy

Your Markdown body stays in the browser; only the parser scripts are fetched from the CDN.

Frequently asked questions

Is raw HTML in Markdown executed?

Untrusted HTML is stripped or sanitized—do not rely on this for authoring CMS posts without your platform’s own sanitizer.

Does Markdown leave my computer?

Parsing libraries load from a CDN; your document text is processed locally in the browser tab.

GitHub flavor parity?

Common tables, fenced code, and task lists render—but GitHub adds extras not mirrored exactly.

Export PDF or DOCX?

Use your OS print dialog from the preview if needed—no dedicated exporter here.
