    1

    Select a File in Finder

    ~16s
    Open Finder on your Mac (the blue and white face icon in the Dock). Navigate to any file — a photo, a PDF, a document, or a video. Click the file once to select it. Do not double-click — that opens the file in an app.
    2

    Press Space Bar to Preview

    ~15s
    With the file selected, press the Space bar on your keyboard. A preview window appears immediately, showing the file's contents. For a photo, you see the full image. For a PDF, you see the pages. For a video, it starts playing automatically.
    3

    Navigate Multi-Page Documents

    ~22s
    If the file is a multi-page PDF or a presentation, scroll with your mouse or trackpad to browse through the pages inside the Quick Look window. Use arrow keys to jump between pages quickly.

    Quick Tip

    Quick Tip: While in Quick Look, press the Left or Right arrow keys to move to the previous or next file in the same folder — great for quickly reviewing a folder full of photos.

    Preview Multiple Files at Once

    ~20s
    Hold Command and click to select multiple files in Finder. Press Space bar. Quick Look shows a preview panel with all selected files as thumbnails. Click any thumbnail to see that file's full preview. Use arrow keys to navigate. To see all thumbnails in a grid, press the index sheet button (four squares) in the top-left corner of Quick Look.
    5

    Close Quick Look

    ~25s
    Press the Space bar again to close the preview window, or press Escape. Quick Look closes instantly. No app was opened, no file was modified — you are right back in Finder where you started.

    Quick Tip

    Quick Tip: From Quick Look, you can open the file in its default app by clicking the "Open with [App Name]" button at the top-right of the Quick Look window — so Quick Look becomes a preview-first approach before committing to opening an app.

    Quick Look is one of the most useful and underused Mac features. Select any file in Finder and press the Space bar — a large preview window opens instantly, showing you the contents of the file without opening any app.

    For photos, Quick Look shows the full-resolution image. For PDFs, it shows the document text and layout. For videos, it plays the video with audio controls. For Microsoft Word or PowerPoint files, it shows the content even if you do not have Office installed.

    Quick Look closes just as fast: press Space bar again or press Escape, and the window disappears without leaving any open applications.

    This is far faster than double-clicking to open a file, waiting for the app to launch, viewing it, then closing the app. Quick Look bypasses all of that in under a second.

    You can even scroll through multi-page PDFs or use arrow keys to browse through multiple selected files in Quick Look mode — great for quickly reviewing a batch of photos to find the best one.
