What does a Markdown previewer do?

A Markdown previewer takes plain text written in Markdown and renders it as HTML so you can verify the formatting before publishing. Markdown Viewer's previewer mirrors GitHub Flavored Markdown so what you see in the preview matches how the document will appear on GitHub, GitLab, and most documentation sites.

Two ways to use the previewer

  1. Paste: copy any Markdown text and paste it into the editor.
  2. Drop: drag a .md or .markdown file from your file manager directly onto the editor.

Either way, the preview renders instantly in the right pane. Toggle between Editor, Split, or Preview view from the top bar.

What the previewer renders

  • Headings, paragraphs, blockquotes
  • Ordered, unordered, and task lists
  • Fenced code blocks with language-aware highlighting
  • Tables with alignment
  • Inline images and external links
  • Footnotes, strikethrough, and autolinks

Sanitization and safety

Markdown Viewer sanitizes raw HTML inside Markdown using rehype-sanitize with a curated allowlist, so opening a third-party document is safe by default.

Frequently asked questions

How accurate is the Markdown preview?
We use react-markdown with the same GitHub Flavored Markdown plugins (remark-gfm) and a curated rehype pipeline, so the rendered output closely matches GitHub.
Can I preview a .md file from my computer?
Yes. Drag the file onto the editor, or use the toolbar's Import action to load it as a new draft.
Does the previewer support code highlighting?
Yes — code blocks are highlighted by highlight.js via rehype-highlight. Add a language hint after the opening fence (e.g. ```ts).
Can I share a preview link?
Yes. Click Share in the editor toolbar to copy a self-contained URL that opens the same document on any device.
