Frequently asked questions
Which Markdown flavor is supported?
It uses the CommonMark / GitHub-Flavored Markdown syntax via the popular “marked” parser — headings, lists, links, images, tables, code blocks, blockquotes, and more.
Can I convert HTML back into Markdown?
Yes. Switch to HTML → Markdown and paste any HTML. It’s converted to clean Markdown using the Turndown library — handy for migrating pages into a docs or blog system.
Why does my HTML preview look plain?
The live preview renders raw HTML without your site’s CSS, so it intentionally looks unstyled. The generated markup is standard and will pick up your own styles once pasted into your project.
Is my content uploaded?
No. Conversion and preview happen entirely in your browser. Nothing you paste is sent to a server or stored.
