## Preview without opening the app

Niraqua DjVu adds a Quick Look preview for `.djvu` files, so you can check a
document straight from Finder:

1. Select a `.djvu` file in Finder.
2. Press the **space bar**.
3. A preview window opens with the document.

Press the space bar again, or **Esc**, to close the preview.

## What you can do in the preview

- Scroll through the pages of the document.
- Click **Open with Niraqua DjVu** in the Quick Look window to open the full app
  when you need search, text recognition, or export.

## Thumbnails in Finder

With the app installed, `.djvu` files also get real thumbnails: the first page
of the document becomes the file's icon, and multi-page documents get a folded
corner, the way Preview shows PDFs. Thumbnails appear in Finder's icon and
gallery views and anywhere else the system shows file icons.

For the wider workflow, see [DjVu readers for Mac and native Finder
integration](https://niraqua.com/djvu/djvu-reader-mac/).

## If the preview is blank

Quick Look previews are generated by the system. If one comes up blank, see
