Frequently Asked Questions

What Markdown features are supported?

Full CommonMark plus GitHub-flavored Markdown: headings, bold, italic, strikethrough, links, autolinked bare URLs, images, fenced code blocks, inline code, blockquotes, ordered/unordered lists, task lists, tables, and horizontal rules.

Is the HTML output safe to use?

Yes. The Markdown is parsed to a syntax tree and rendered through a sanitizer (rehype-sanitize) that drops scripts, event-handler attributes, and other unsafe markup, so pasting untrusted Markdown can't inject active content into the output.

Can I preview the rendered HTML?

Yes. Switch to the "Preview" tab to see the HTML rendered in the browser, or stay on "Raw HTML" to see the generated markup.

Is my data sent to a server?

No. All Markdown parsing and HTML generation happens entirely in your browser. No data is sent to any server.
