⚙️ How It Works
Begin typing standard Markdown syntax in the left-hand editor pane. As you type, the right-hand preview pane automatically updates in real-time, displaying exactly how your structured formatting (headers, bolding, lists) will eventually render on the web.
❓ Frequently Asked Questions
What Markdown syntax is supported?
We support standard CommonMark syntax alongside popular GitHub Flavored Markdown (GFM) extensions, including data tables, strikethrough text, interactive task lists, and automatic URL linking.
Can I export my document as raw HTML code?
Yes! Once you finish writing your Markdown, simply click the 'Copy HTML' button to immediately copy the fully compiled, production-ready HTML markup to your clipboard.
Are my documents saved automatically?
No, this tool acts as a stateless scratchpad. Your written text is only held temporarily in your browser tab's active memory and is not persisted to any external database.
Does the Markdown Previewer work offline?
Yes, the Markdown Previewer is fully functional offline. Because this tool runs entirely in your browser, no data is ever uploaded to external servers. Once the page is loaded, you can seamlessly continue using it without an active internet connection. You can also install Knicknaks as a Progressive Web App (PWA) for native-like offline access.
