Core Features

Focused on Markdown reading, done right

No heavy editor features—just a quiet, efficient reading window. The following features are available in both editions; the Pro Edition additionally offers Mermaid diagrams and math formula (KaTeX) rendering.

Live Reload

After saving a file, it automatically re-renders with no manual refresh needed. SSE push makes changes visible instantly.

Double-Click to Open

After installation, it auto-registers the .md file association. Then just double-click any Markdown file to preview.

Document Outline

Automatically extracts headings to generate a floating table of contents. Click to jump, and the current section is auto-highlighted as you scroll.

Jump to Source

Select text and press Ctrl+E to open your editor and jump directly to the corresponding line.

Local Images

Automatically loads local images in the same directory as the Markdown file, supporting PNG, JPG, SVG, GIF, and more.

Dark / Light Themes

Switch with one right-click. Outline and dialogs are fully adapted, and your preference is saved automatically.

Export PDF

Right-click to print/export, making it easy to archive or share documents with others.

Clean & Ad-Free

Runs locally; your files are never uploaded. No account needed, no tracking, privacy-first.

Why mdview

Just want to read? Why open an editor?

Every time you double-click a .md file, you probably just want to read it, not edit it.

VS Code / Typora

Takes 3–5 seconds to launch and loads tons of plugins and features. Overkill for just glancing at a README.

Browser + Extension

Can't directly double-click a local .md file; every time you have to drag or copy-paste—tedious.

mdview

Double-click to open, instant response. 1.6 MB installer, zero config, press Esc to exit—as handy as macOS Quick Look.

Privacy First

Your files never leave your computer

mdview runs 100% locally. It only starts a temporary HTTP server on localhost to render the page—your Markdown content is never uploaded to any server. No account, no tracking, no telemetry.

How to Use

Three steps to reading

Simpler than setting up an environment, faster than opening a browser

1

Download the Installer

Download the mdview-setup.exe installer.
Recommended: save it to a common folder before running.

2

Run the Installer

Run the installer to automatically complete installation and .md file association registration,
and a welcome window will confirm the status.

3

Double-Click .md Files

From then on, double-click any Markdown file
to view it live.

About the Windows Security Prompt

Windows may show a SmartScreen prompt when installing or running mdview for the first time. Click More info → Run anyway. This software runs entirely locally and does not upload any data.

FAQ

Questions you might have

Is mdview free?
mdview offers two editions: the Community Edition is completely free, ad-free, and requires no registration, with all core reading features included; the Pro Edition includes all Community features and additionally supports Mermaid diagrams and math formulas. The Pro Edition offers 100 free trials, after which you can click "Remind me later" to continue using it, or unlock permanently for $0.99 USD. See edition comparison →
What's the difference between the Community and Pro editions? Which should I choose?
Both editions share the same core functionality and are built from the same source; the Pro Edition additionally supports Mermaid diagrams (flowcharts, sequence diagrams, Gantt charts) and math formula rendering (KaTeX, LaTeX syntax), which are not included in the Community Edition. The main difference is how you get them: the Community Edition is free forever with optional sponsorship; the Pro Edition is $0.99 USD to unlock after 100 free trials. They are the same product and will overwrite each other during installation, so choose one.
· Most users choose the Pro Edition—it adds two core rendering features, unlocks permanently for $0.99, and future updates are free for existing purchasers.
· Need Mermaid diagrams / math formulas / want to support the developer? Choose Pro Edition, try it 100 times first, then decide.
Android only offers the free Community Edition.
Windows says "Windows protected your PC." Is it safe?
This is a Windows SmartScreen prompt because the program does not have a commercial code signing certificate (they are expensive). Click "More info" → "Run anyway" to use it normally. mdview runs entirely locally and does not connect to any external server to upload your file content.
What are the system requirements?
Windows: Windows 10 or Windows 11, requiring the WebView2 runtime (preinstalled on Windows 11 and most Windows 10 systems; the system will prompt you to install it if missing).
Android: Android 7.0 and above.
How do I unassociate .md files?
Method 1: Right-click in the preview window → Open Settings → Unbind.
Method 2: Run the command mdview --unbind.
Method 3: Run mdview --uninstall to also remove the context menu.
How is it different from Typora / VS Code?
Typora and VS Code are powerful editors with comprehensive features but slower startup. mdview focuses on fast reading: opens in seconds with a double-click, exit with Esc—perfect for when you just need to view a Markdown file (READMEs, docs, notes). They complement each other, not conflict.
Does it support Mermaid diagrams and math formulas? Which edition?
The Community Edition supports basic Markdown syntax, tables, syntax-highlighted code blocks, local images, and more; Mermaid diagrams (flowcharts, sequence diagrams, Gantt charts) and math formulas (KaTeX, LaTeX syntax) are exclusive to the Pro Edition. The rendering engines are downloaded on first use and then available offline.
