[nahid619]

A fast, tabbed Markdown viewer for Windows. Double-click any .md file and it opens straight into a rendered preview. A few MB installed, no Electron, no telemetry, no account.

⬇️ Download

File	For
MD-Viewer_0.3.0_x64-setup.exe	Windows 10 / 11, 64-bit

Download the .exe below, run it, done. It installs for your user account only — no admin prompt — and registers .md and .markdown file associations automatically.

To make it the default .md app: right-click any .md file → Open with → Choose another app → pick MD Viewer → tick "Always use this app".

SmartScreen warning? The installer isn't code-signed (a certificate costs a few hundred dollars a year). Click More info → Run anyway. Or build it yourself from source — instructions are in the README.

What's in 0.3.0

A correctness and performance release. Nothing about how the app looks or which keys do what has changed; almost everything about how it behaves under load has.

• Fixed a layout bug where a single long code line or a wide table could silently widen the whole window — slicing prose mid-word against the right edge, and shoving the find bar off-screen when you pressed <kbd>Ctrl</kbd>+<kbd>F</kbd>.
• Event-driven file watching replaces the old 1.8 s polling loop, so there are zero CPU wakeups while a document just sits there being read.

Full details in the changelog.

⭐ If this is useful to you

MD Viewer is free and MIT-licensed. I built it because I was tired of opening .md files in Notepad, and I put it out there in case anyone else was too.

If it saves you some time, the single most useful thing you can do is star the repository — it takes one click, and it's what makes the project findable for the next person searching for a Markdown viewer.

Also genuinely helpful:

• 🐛 Report a bug or request a feature — run doctor.cmd first and attach doctor-report.txt, it answers most of what I'd otherwise have to ask
• 🔗 Share it with someone who keeps opening .md files in Notepad
• 💬 Tell me what you're using it for
