Your files never left your device
No. Everything runs in your browser - your file never leaves your device. How this is verifiable
Markdown is a lightweight text format: with a few characters like # for headings, * for lists or ** for bold you write structured documents that stay readable everywhere. HTML, by contrast, is the language every browser renders directly. This tool renders your Markdown into a complete, standalone HTML document.
The output is a self-contained .html file with charset, viewport and a lean, readable stylesheet - you can open it in a browser or pass it on right away. Headings, lists, links, tables, quotes and code blocks follow the CommonMark standard; any raw HTML you wrote in your Markdown is preserved.
Everything happens locally in the browser, nothing is uploaded - even offline. Your text never leaves your device, unlike online converters that load your files onto third-party servers.
