How to keep a screenshot on top of other windows on Mac

You need to look at one thing while typing into another — an invoice, a spec, an error message. Here's how to make a screenshot float above every window on macOS.

Short answer: macOS has no built-in "always on top" option for screenshots or windows. The native screenshot thumbnail disappears after a few seconds, and Preview windows go behind whatever app you click next.

To pin a screenshot above every window, use a floating-screenshot app. With FloatSnap ($5, 14-day free trial) you press ⌘⇧9, drag over the area you need, and it stays on top until you click it away.

Why macOS can't do this by itself

Windows has had "always on top" utilities for decades, and many Linux window managers support it out of the box. macOS doesn't. Apple's window system lets apps create floating panels, but there is no menu item or keyboard shortcut that lets you pin an arbitrary window or image above the others.

The built-in options come close but don't solve it:

Method 1: Pin it with FloatSnap (fastest)

FloatSnap is a 1.4 MB menu bar app built for exactly this one job. Every capture becomes a floating window by default — there's no extra "pin" step.

  1. Install. Download FloatSnap, drag it to Applications, and open it. macOS will ask for Screen Recording permission (System Settings → Privacy & Security → Screen Recording).
  2. Capture. Press ⌘⇧9 or click the menu bar icon, then drag over the area you want to keep visible.
  3. Place it. The capture appears as a floating window above every app. Drag it to a corner, over a spare bit of screen, wherever it helps. You can resize it and stack several at once.
  4. Use it. Click into your spreadsheet, editor, or browser and keep working — the screenshot stays on top. Right-click it for OCR text extraction, annotation, copy, or save.
  5. Dismiss. Click it once and it's gone. Nothing is saved to your Desktop unless you choose Save. (If you're worried about closing it by accident, right-click → Pin in place.)

Because nothing is stored or uploaded, it's safe to float sensitive things — client invoices, bank statements, internal docs. The app has no account, no analytics, and no cloud component.

Method 2: Use a full screenshot suite

If you want screen recording, scrolling capture, and a big annotation toolkit too, the larger screenshot apps also have a pin feature — it's just one option among many rather than the default behavior.

Method 3: No-install workaround

If you can't install anything (say, a locked-down work Mac), the best you can do is window tiling:

  1. Take the screenshot with ⌘⇧4 and open it in Preview.
  2. Hover over Preview's green button and choose a left/right tiling option (or use Window → Move & Resize).
  3. Tile the app you're typing into on the other half.

It works, but you lose half your screen, and you'll need to delete the screenshot file from your Desktop afterward.

Frequently asked questions

Can macOS keep a window always on top?

Not natively. macOS has no general always-on-top setting. Picture in Picture only works for video, and Split View and tiling place windows side by side rather than on top. You need a third-party app.

Does the macOS screenshot thumbnail stay on screen?

No. It disappears after a few seconds and saves to your Desktop (or whichever folder you chose in the ⌘⇧5 Options menu). It can't be pinned.

Will a pinned screenshot stay on top of full-screen apps?

With FloatSnap, floating screenshots stay above other windows as you switch apps. Each floater stays on top within its current Space and display.

Does a floating screenshot get saved to my Desktop?

Not with FloatSnap. Screenshots exist only on screen until you dismiss, copy, or save them.
