How to view a Markdown file online
- Click Open .md file, drag a file onto the tool, or paste your Markdown into the text box.
- The rendered document appears next to the source as you type or paste.
- Switch between light and dark preview, or use Print / Save as PDF to keep a copy.
The viewer reads files with .md, .markdown and plain-text extensions up to 5 MB. Diagrams, math and code highlighting only load when your document uses them, which keeps simple files fast.
New to the format? Read what an .md file is, see how to open .md files on Mac, iPhone and iPad, or keep the Markdown cheat sheet open. For diagram syntax, see Mermaid diagrams in Markdown, or draw one in the Mermaid live editor.
Frequently asked questions
- Is my file uploaded anywhere?
- No. The file is read and rendered by your browser. The text of your document is never sent to a server, and the page does not store it.
- What can this Markdown viewer render?
- GitHub Flavored Markdown (tables, task lists, strikethrough, autolinks), Mermaid diagrams in ```mermaid code blocks, LaTeX math written between dollar signs, and syntax-highlighted code blocks.
- How do I save a rendered .md file as a PDF?
- Use the Print / Save as PDF button, then choose “Save as PDF” as the destination in your browser’s print dialog. The print view contains only the rendered document, on white paper.
- Can I open MDX files?
- You can open them, but they are shown as plain Markdown. JSX components inside an .mdx file are not run.
- What is the difference between this and the OpenMark app?
- This page is a quick viewer. OpenMark is a native Mac app that opens .md files with a double-click, previews them in Finder with Quick Look, lets you edit the source, and works offline; an iPhone and iPad reader is included. It is $9.99 once.
