Preview

Everything reading needs. Nothing it doesn't.

No toolbars, no buttons, no clutter — the window is your document. Everything lives one right-click away.

Live refresh on save

Save in any editor and mdview re-renders instantly over SSE — keeping your scroll position, so you never lose your place.

Outline, history & favorites

A floating outline tracks your position as you scroll. History is grouped by day like your browser, and favorites pin the docs you live in.

9 color themes + dark mode

Glacier, Forest, Sunset, Typewriter and more — switch themes from the right-click menu. Your preference is remembered per app, everywhere.

Type that fits your eyes

Pick any installed font, Ctrl+scroll for font size, Alt+scroll for column width. Text truly reflows — no blurry bitmap zoom.

Renders the whole document

Tables with alignment, footnotes with back-links, local images, and syntax-highlighted code blocks with copy, wrap and line numbers. GBK/GB18030 files open cleanly too.

Export to PDF

One right-click turns what you're reading into a PDF — exactly as styled on screen, ready to share or archive.

Also: drag-and-drop open · Ctrl+O · single window per file · remembers where you stopped reading · auto update checks

mdview history panel: recently opened Markdown files grouped by day, like browser history

Why mdview

Quick Look for Markdown

You double-click a .md file to read it — not to boot an IDE.

mdview Typora / VS Code Browser extension
Install size 2.0 MB 100–400 MB — (but needs a browser)
Double-click a .md file Instant 3–5 s of editor startup Drag or copy-paste each time
Reading-first UI Zero chrome Toolbars, panels, tabs Browser UI around it
Built for Reading Writing code / docs Occasional preview

They complement each other — keep your editor for writing, use mdview for the 90% of times you just read.

Privacy first

Your files never leave your computer

mdview runs 100% locally. It starts a temporary server on localhost purely to render the page — no uploads, no account, no ads, no tracking.

How it works

Reading in three steps

1

Install

Grab the 2.0 MB installer. One click, no options to ponder.

2

Nothing to set up

mdview associates .md files for you automatically. No account, no config.

3

Double-click & read

Any Markdown file now opens rendered, like a webpage. Esc closes it.

Seeing a SmartScreen prompt? That's Windows flagging apps without a costly code-signing certificate. Click "More info" → "Run anyway" — mdview runs entirely locally.

FAQ

Questions, answered

How do I open .md files on Windows?
Install mdview once and it associates .md files for you. From then on, double-click any Markdown file and it opens rendered like a webpage — no editor, no browser extension, no configuration. More detail: 3 ways to open .md files.
Is mdview free?
Yes. The Community Edition is free forever with the full reading experience. The Pro Edition adds Mermaid diagrams, KaTeX math and two editing modes (F2 Live Edit, F3 split-screen) for a one-time $9.99 lifetime unlock (per-device buyout, free upgrades forever) — with 100 free trial opens first, and a dismissible "Maybe Later" prompt after that. It never hard-locks.
How is it different from Typora or VS Code?
Typora and VS Code are editors — powerful, but heavy when you only want to read. mdview is a dedicated viewer: a 2.0 MB installer that opens in under a second and closes with Esc. Think Quick Look for Markdown. They complement each other. Full breakdown: mdview vs Typora vs VS Code.
Does mdview upload my files?
No. mdview runs 100% locally. It only starts a temporary server on localhost to render the page — your Markdown never leaves your computer. No account, no ads, no tracking.
What about Windows SmartScreen warnings?
SmartScreen flags apps without an expensive code-signing certificate. Click "More info" → "Run anyway". mdview runs entirely locally and uploads nothing.
What are the system requirements?
Windows 10/11 with the WebView2 runtime (preinstalled on Windows 11 and most Windows 10 PCs) · macOS 11 Big Sur or later on Apple Silicon (M1 and later; Intel Macs are not supported). New to Markdown? Learn it in 3 minutes.
