Out of the box, pressing Space on a Markdown file in Finder shows raw text: hashes, asterisks and all. Downer replaces that with a proper page.

What it previews

  • Markdown files, with headings, tables, task lists, code and links formatted
  • Mermaid files (.mmd and .mermaid), drawn as diagrams
  • LaTeX papers (.tex), shown as readable pages with their math

The preview is drawn the same way as the app, so Quick Look shows a file the way Downer will. It follows your Mac’s light or dark appearance.

Skim a folder without opening anything

Select a file, press Space, then use the arrow keys to move through the folder. It’s the fastest way to find the right README, notes file or diagram before you open it.

When you find the one you want, open it in Downer for the full reader: the map of headings, find, your chosen theme, and the editor.

One limit

Quick Look previews don’t show images stored beside the file, such as a screenshot in an images folder. Open the file in Downer and every image appears.

Questions

Do I need to set anything up?

Install Downer and open it once. The first-run setup shows whether its Quick Look preview is on, with a shortcut to System Settings if it isn't.

Why is my preview still plain text?

Some other apps, often code editors, add their own Markdown previews, and macOS may pick theirs. Turn the other app's Quick Look extension off in System Settings and Downer's takes over.

Are images shown in Quick Look?

Not all of them. Images stored next to the file aren't shown in the Quick Look preview. Open the file in Downer and every image appears.
