常見問題
關於 markdown 編輯、即時預覽與文件建立的一切知識
What Markdown syntax is supported?
All standard Markdown (CommonMark): headings, bold, italic, links, images, code blocks, lists, blockquotes, tables, and horizontal rules. We also support GitHub Flavored Markdown extensions like task lists, strikethrough, and fenced code blocks with syntax highlighting.
Does it support syntax highlighting in code blocks?
Yes. Fenced code blocks with a language tag (```python, ```javascript, etc.) are rendered with full syntax highlighting. We support 100+ programming languages including Python, JavaScript, TypeScript, Go, Rust, and SQL.
Can I use this for GitHub README files?
Absolutely. The previewer uses GitHub Flavored Markdown (GFM) which matches how GitHub renders README.md files. You can preview your README exactly as it will appear on GitHub, including tables, task lists, and emoji shortcodes.
Does it support math equations (LaTeX)?
The previewer supports standard Markdown. For LaTeX math rendering, you'd need a specialized tool or extension. However, inline code and code blocks work well for displaying formulas in a monospaced format.
Can I export the rendered output?
You can copy the rendered HTML output for use in websites, emails, or documentation. The preview shows exactly what the final rendered Markdown will look like in a browser or on GitHub.
Is my content private?
Yes. All Markdown rendering happens locally in your browser. Your documents are never sent to any server. This is safe for previewing internal documentation, private READMEs, or any sensitive content.
