Quick Look

Peekdown includes a Quick Look extension that renders markdown files directly in Finder. Press Space on any markdown file to see a styled preview — no need to open the app.

The extension is enabled automatically when you install Peekdown. It uses the same GitHub-style theming as the main app, including light and dark mode support.

Links in Quick Look

External links (http://, https://) work in Quick Look — clicking one opens it in your default browser.

Links to other local files don't navigate inside Quick Look. macOS sandboxes Quick Look previews and doesn't let extensions follow file links between documents. To follow a local link, open the document in Peekdown.

Quick Look Not Working?

If pressing Space shows plain text instead of a rendered preview, another app's Quick Look extension may be overriding Peekdown's. Code editors like Nova, VS Code, or Sublime Text often include their own Quick Look extensions for markdown files.

To fix this:

1. Open System Settings > Login Items & Extensions
2. Find the Quick Look section
3. Disable the conflicting app's extension

Peekdown's extension will then handle markdown previews.

If Quick Look still isn't working after disabling other extensions, try resetting the Quick Look cache by running this command in Terminal:

qlmanage -r
