Render Markdown in macOS Quick Look. Free & open source.

A tiny macOS Quick Look extension. Select a .md file in Finder, press space, and read it rendered the way it was meant to look — headings, code, tables and task lists included. No app window, just a menu-bar helper that stays out of the way.

Pressing spacebar on Markdown files in Finder shows rendered Quick Look previews with headings, code blocks, tables and task lists
Spacebar on a .md file in Finder → rendered preview.

What it does

  • Rich rendering. Headings, lists, task lists, blockquotes, links, bold, italic, strikethrough and inline code.
  • Syntax-highlighted code. Fenced code blocks highlighted with a clean GitHub-style theme, light and dark.
  • Real tables. GitHub-flavored Markdown tables render as native AppKit tables — not raw pipes.
  • Sandboxed & offline. Runs in a sandboxed Quick Look extension with no network access. A menu-bar helper, no Dock icon.

Install

  1. Download & open the disk image. Drag Markdown QuickLook into your Applications folder.
  2. Launch it once. Open it from Applications. It lives in the menu bar and registers the Quick Look extension.
  3. Press space. Select any .md file in Finder and hit space. If an old preview is cached, use the menu-bar item → Reset Quick Look Cache.
