Does Clear Shelf delete my screenshots?

No. It only empties the Shelf; your files stay where they are.

How many shots does it keep?

The last 20, for as long as you choose: 1 hour, 24 hours or 7 days.

Every shot slides onto the Shelf beside the editor. Drop in any image, or drag one out to Finder or any app.

The Shelf is a strip beside the screenshot editor with your recent shots, so none get lost between captures.

Drop in any image (or press ⌘V) and it joins the Shelf, ready to edit. Drag one onto the canvas, or out to Finder or any app.

It keeps your last 20 shots for 1 hour, 24 hours or 7 days. Clearing it never touches your files.
