What Markdown Previewer does
Markdown is a lightweight text format that turns simple punctuation into headings, lists, links, tables, quotes, and code. The preview is converted to HTML and sanitized before it enters the page.
Examples
- Draft a README with headings, links, lists, and fenced code.
- Preview a Markdown table before publishing documentation.
- Download either the original `.md` file or sanitized rendered HTML.
Frequently asked questions
Is my input uploaded?
No. This tool processes its input locally in your browser. Normal page requests do not include the contents you enter or select.
Can Markdown execute HTML or scripts here?
No. Rendered HTML is sanitized, script elements are removed, and unsafe attributes are not executed.
Will it work in every browser?
The tool uses modern browser APIs. Current Chromium, Firefox, and Safari releases provide the best support; the page displays a clear error when a required capability is unavailable.
