It's widely used for README files, documentation, blog posts, and note-taking.
No — everything runs entirely in your browser. Nothing is uploaded to a server. However, refreshing the page will clear your content, so be sure to copy your Markdown or HTML before navigating away.
This tool supports headings (H1–H6), bold, italic, bold-italic, strikethrough, inline code, fenced code blocks with language hints, links, images, unordered lists, ordered lists, blockquotes, and horizontal rules. The parser is a custom lightweight implementation — not a full CommonMark spec, but suitable for everyday use.
Use the "Copy Markdown" button to copy the raw Markdown source text, or click "Copy HTML" to copy the fully rendered HTML markup that you can paste directly into a website or CMS. Both options copy to your clipboard instantly.
