Frequently Asked Questions

What Markdown syntax is supported?
We support CommonMark syntax including headings, bold, italic, links, images, code blocks (with language hints), blockquotes, ordered and unordered lists, tables, horizontal rules, and inline code.
Can I use this for email HTML?
The generated HTML is clean and semantic, suitable for most uses. For email, you may want to inline styles since many email clients strip CSS classes.
Is my data sent to any server?
No. All conversion happens entirely in your browser. No data is transmitted anywhere.
