Open your .md file,
no fuss.
Someone sent you an .md file and you're not sure what to do with it. MDReader opens it, makes it look beautiful, and lets you print it. That's it.

What even is an .md file?
An .md (Markdown) file is a document written in plain text with simple formatting signals — like # Heading or **bold**. Developers and writers use them constantly. When you open one in Notepad, it looks like a mess. MDReader reads all those signals and shows you the formatted document, exactly the way the author intended.
What MDReader does
Headings, bullet points, tables, code blocks — everything is rendered cleanly and clearly. It just looks right.
Need a paper copy? Print directly from MDReader with properly formatted output — no stray symbols, no broken layout.
Set MDReader as your default for .md files and they open instantly — no menus, no extra steps.
Open several files at once and switch between them with tabs — familiar, simple, no learning curve.
Installs in seconds, opens instantly. No subscription, no account, no cloud. Just a small app that does its job.
MDReader doesn't edit your files, sync them anywhere, or ask for permissions. It reads. It prints. That's all.
Getting started
Click the download button below and save the installer file to your computer. The MSI installer is recommended for most people.
Double-click to install. Windows may show a security warning the first time — see the note below for how to safely click through it. The whole process takes about 30 seconds.
Use the Open File button in the app, or go to File → Open. You can also drag an .md file directly onto the MDReader window.
Your document is right there, formatted and ready. Print with Ctrl+P or use File → Print whenever you need a copy.
A note on Windows security
Because MDReader is an independent app from a small developer, Windows SmartScreen may show a warning the first time you install it. This doesn't mean anything is wrong — it just means Windows doesn't recognize the publisher yet. Here's how to proceed.
You may see a dialog that says "Windows protected your PC" or "Unknown publisher." This is Windows SmartScreen. It appears for any new app that hasn't yet built up enough install history with Microsoft — not because anything is wrong with the file.
When the SmartScreen dialog appears, look for the small "More info" link and click it. This expands the dialog to show more options.
A "Run anyway" button will appear at the bottom. Click it to continue with the installation.
The standard Windows installer will open. Follow the prompts — it takes about 30 seconds and installs MDReader like any other app.
Opening .md files automatically
Once MDReader is your default, double-clicking any .md file opens it automatically — no need to go through File → Open each time. If another app is currently set as the default, here's how to switch it.
You just need one .md file to work with — it can be the one you were sent, or any other.
Right-click the file icon to open the context menu.
Hover over Open with in the menu, then click Choose another app from the submenu that appears.
MDReader should appear in the list. If you don't see it, scroll down and click More apps. If it's still not listed, click Look for another app on this PC and navigate to where MDReader is installed — usually C:\Program Files\MDReader.
Make sure the checkbox at the bottom — "Always use this app to open .md files" — is ticked before clicking OK. From now on, double-clicking any .md file will open it straight in MDReader.
MDReader is free and always will be. But if it's made your life a little easier, I'd appreciate the support — and if you can spare one, I'll get a pup cup for Nagi and tell her it's from you.
