Markdown Viewer for Windows

MarkView is a free, native Windows app that opens .md files in a clean, readable view — like Acrobat Reader, but for Markdown. Double-click any .md file and it just opens. No editor, no browser extension, no cloud accounts.

Why a native Windows app for Markdown?

Markdown shows up everywhere — AI chat exports from ChatGPT and Claude, GitHub README files, project documentation, meeting notes, team handbooks. Out of the box on Windows, double-clicking a .md file opens it in Notepad, where headings, tables, and code blocks come out as raw text littered with # symbols and pipe characters.

MarkView is a focused Windows app that fixes that. It registers as a handler for .md files so they open the way they were meant to look — with proper headings, formatted tables, rendered diagrams, and syntax-highlighted code. You don't have to launch a Markdown editor, fire up VS Code, or paste content into a web tool just to read it.

.exe and .msi for IT-managed environments

Two Windows builds are available:

  • .exe installer — the standard option for individual users. Supports per-user install (no admin rights required) or per-machine install.
  • .msi package — intended for IT-managed deployment via Group Policy, Microsoft Intune, SCCM, or any other Windows deployment tool that consumes .msi. Both packages install the same application.

How to open .md files on Windows

  1. Download the Windows build — .exe installer for personal use, or .msi if your IT department deploys .msi packages.
  2. Run the installer and accept the defaults.
  3. Double-click any .md file. It opens in MarkView.

Make MarkView the default Markdown app on Windows

MarkView includes a built-in Set as Default option in its menu that wires this up in one click. Manual steps if you prefer:

  1. Right-click any .md file in File Explorer.
  2. Choose Open With.
  3. Click Choose another app.
  4. Pick MarkView from the list.
  5. Check Always use this app to open .md files.
  6. Click OK.

From then on, every .md file opens in MarkView with a double-click — from File Explorer, the desktop, the Downloads folder, Outlook attachments, anywhere else.

What MarkView renders

  • GitHub-flavored Markdown — headings, lists, tables, blockquotes
  • Syntax highlighting for code blocks across 180+ languages
  • Mermaid diagrams (flowcharts, sequence diagrams, class diagrams)
  • LaTeX math equations rendered with KaTeX
  • Auto-generated table of contents and a file browser sidebar
  • Light and dark themes that follow your Windows appearance

Privacy on Windows

MarkView runs entirely on your PC. Files you open never leave the machine — no upload, no cloud, no server round-trip. There are no accounts to create. The only network traffic is an occasional check for a new version of MarkView itself, which you can disable in preferences.

Frequently asked questions

Is MarkView for Windows really free?

Yes. MarkView is free to download and use, with no trial limits, no paid tier, and no upsell. If you find it useful, there's an optional "buy me a coffee" link on the home page.

Is MarkView a browser extension or a Windows app?

MarkView at markview.io is a native Windows app — it installs through a normal .exe or .msi installer, registers as a handler for .md files, and lives in your Programs list like any other Windows app. It is not a browser extension. Browser extensions for Markdown viewing also exist, but they only work inside the browser; MarkView opens .md files directly from File Explorer, Outlook attachments, the desktop, the Downloads folder, and anywhere else Windows asks "what should I open this with?"

Does MarkView work on Windows 10 and Windows 11?

Yes. MarkView is built and tested on current versions of Windows 10 and Windows 11.
