关于此工具
Markdown 预览器实时把 CommonMark / GitHub 风格 Markdown 渲染为 HTML,让你在推送 README、博客或文档前先看效果。Markdown 是技术写作的通用语言,快速预览能省下发布后再修的往返。
使用方法
- Type or paste Markdown into the editor on the left.
- The preview pane on the right renders updates instantly.
- Use standard syntax: # headings, **bold**, `code`, ``` fenced blocks ```, [links](#).
- Click Copy HTML to grab the rendered output for use in CMS or email.
- Iterate until the layout looks right, then commit the Markdown source to your repo.
常见用例
- Drafting a README before pushing to GitHub or GitLab.
- Previewing a blog post for a static site generator like Hugo or Astro.
- Composing a release note that will be pasted into GitHub Releases.
- Checking a Pull Request description renders correctly.
- Producing HTML email content from a Markdown source for a newsletter.
- Verifying a documentation page before opening a Docs PR.
常见问题
Q. Does this support GitHub-flavored extensions like task lists?
A. Yes — checkboxes, fenced code blocks, autolinks, and tables work. Some platform-specific features (alerts, mermaid diagrams) may render differently on GitHub itself.
Q. Why does my code block lose syntax highlighting?
A. The previewer renders structure, not full syntax themes. GitHub, Gitea, and most static site generators apply their own highlighting on top.
Q. Can I render math (LaTeX)?
A. Not in the basic preview. Some Markdown processors integrate KaTeX or MathJax — check whether your target platform supports it before relying on it.
Q. Is anything sent to a server?
A. No. The Markdown is parsed and rendered entirely in your browser.
