Download free - v1.3.12

Apple checks every release before it reaches you. Less than 5 MB to download. Or the .zip.

The app

Open, edit and preview the same local file.

The actual app rendering a local Markdown file, switching to source editing and previewing the file in Finder Quick Look.

Homebrew

Install the notarized app from the command line.

brew install --cask px7digital/tap/px7-markdown-viewer

The public PX7 tap pins version 1.3.12 and verifies the downloaded ZIP against its published SHA-256 checksum. Homebrew installs the same app as the direct download above.

What it does

Open. Read. Edit. Done.

👀

Double-click any .md - CommonMark + GitHub flavour, in a clean reading theme that follows light/dark.

🔍

Quick Look preview

Tap space on any .md in Finder and it renders right there - the same theme, no need to open the app. Comparing tools? See every Markdown Quick Look option on the Mac.

✍️

Source editing

Press ⌘E to edit the source, ⌘S to save. It never silently overwrites a file that changed underneath you.

Local image rendering

Pictures next to your note render in place - resolved safely from the note's own folder.

📄

Offers to open every Markdown file on your Mac, so they stop opening as raw text.

Questions about PX7 Markdown Viewer

What is PX7 Markdown Viewer?
Open .md files as rendered Markdown, preview them in Finder Quick Look, and edit the source. Free native Mac app; local files and no account.
Where does PX7 Markdown Viewer do its work?
PX7 Markdown Viewer works directly with the Markdown files stored on your Mac.
How much does PX7 Markdown Viewer cost?

Which Macs can run PX7 Markdown Viewer?

How do I open an .md file on a Mac?
Install PX7 Markdown Viewer, then double-click the .md file in Finder. It opens as rendered Markdown; press Command-E to edit the source and Command-S to save it. The app is free and works locally.
How do I preview Markdown files in Finder?
Install a Quick Look extension and pressing Space on a .md file renders it instead of showing the source. PX7 Markdown Viewer adds that preview and also opens .md files on double-click.
Why does Quick Look show raw Markdown text?
macOS has no built-in Markdown renderer, so Quick Look falls back to plain text and you see the asterisks and hashes. A Quick Look extension replaces that fallback with a rendered view.
Can I edit a Markdown file directly from its preview?
Yes — ⌘E switches to the source and ⌘S saves it, so a small correction does not need a separate editor. Images are resolved from the note's own folder.
Is there a free Markdown viewer for Mac?
PX7 Markdown Viewer is free. It renders CommonMark and GitHub-flavoured Markdown, runs entirely on your Mac, and needs no account.
Is PX7 Markdown Viewer the same app as MacMD Viewer?
No. PX7 Markdown Viewer is a separate app made by PX7 Digital and is free. MacMD Viewer is an unrelated product from another developer with its own pricing.
