Pin a screenshot above your other Mac windows

Keep a reference image floating on screen while you work, then move it, resize it, or close it when you are done.

Some shots are references, not files you send. A design, a ticket, a diagram, or a list is more useful if it stays visible while you work in another app. Pin does that.

Pin the capture

Take the screenshot, or reopen one from History.
Choose pin from Quick Access. You can also set pin as the default action after a shot.
Drag the image where you can see it. Resize it if it covers the window you are using.

The pinned image floats above other apps. Close it when you no longer need the reference. The capture remains in History.

Change how the pin looks

In Advanced settings you can add rounded corners, a shadow, or a border on pinned images. That makes the reference easier to tell apart from the window underneath it.

Annotate first if you need marks

Add arrows or blur before you pin, if the reference should already show what to look at. You can also copy or save the same image. Nothing is uploaded. Install Shoverlay on the Mac App Store.
