What is an online Markdown viewer?

An online Markdown viewer renders .md files as a readable web page — without making you set up a text editor or static site. Markdown Viewer is exactly that, with three additions writers and developers rely on:

  1. Live editing. It's not just a read-only viewer — you can tweak the file in place.
  2. Format and lint tools. Beautify, outline, and link-check what you're reading.
  3. Privacy. The file you drop is processed in your browser and never uploaded.

Three ways to view Markdown

  • Drag and drop: drop the file anywhere on the editor.
  • Paste: paste the raw Markdown text into the editor.
  • Share link: open a shareable URL someone sent you.

Reading experience

The preview is styled with the Tailwind CSS Typography plugin and tuned for screen readability — comfortable line length, sensible heading scale, and high-contrast colors in both themes.

Power features for power users

  • Outline navigator — jump between headings with one click.
  • Word count, character count, and reading time in the status bar.
  • Print to PDF with a clean, print-ready layout.

Frequently asked questions

Is it safe to open Markdown files in the browser?
Yes. The HTML rendered from your Markdown is sanitized with rehype-sanitize using a strict allowlist, so even if a document contains raw HTML it won't execute scripts.
Can the viewer open files larger than 1MB?
Yes, but very large files (10MB+) may take a moment to render on slower devices because everything happens client-side.
Does the viewer work on mobile?
Yes. The layout adapts to small screens and you can switch between editor and preview using the view toggle.
How do I share a Markdown file?
Open the file in the editor and click Share in the toolbar. A self-contained URL is copied to your clipboard — anyone with the link can view the same file.
