One Shot Capture on Mac
TrarrenShot One Shot starts one Mac capture flow: click a window, drag to select a region, or press F to capture the display where the capture started. If the window you choose is behind another app, TrarrenShot brings its captured image forward before opening the Inline Editor, where you can refine the final capture area.

Best for
- Capture one app window without choosing a separate capture mode first.
- Select a visible part of a document, webpage, or app.
- Capture the display under your pointer when you start One Shot.
One Shot puts window, region, and full-screen capture into one flow. Start once, decide what to capture directly on screen, then continue in the Inline Editor, clipboard, or a saved file.

Capture anything from one flow
- Window — hover a window to highlight it, then click to capture it.
- Region — drag a rectangle over the area you want.
- Full screen — capture the active display.
If you choose a window that is behind another app, TrarrenShot brings the window's captured image forward before continuing to the Inline Editor.
Use capture shortcuts without leaving the flow
An on-screen shortcut hint keeps the available actions visible while you capture. Press C to copy the HEX color under the pointer, P to open Live Canvas, or ESC to cancel. A magnifier helps you aim precisely.
Continue in the Inline Editor
When your post-capture setting opens the editor, you can annotate the screenshot immediately and refine the final capture area before exporting, without starting the capture again. You can also edit the displayed capture dimensions directly when you need a more precise final size. The same workflow can detect a QR code or recognize text with OCR from the captured content.
Choose what happens next
Based on your output setting, the captured result opens in the editor, copies to the clipboard, or saves to a file.
After output, Preview can keep the result nearby so you can review it, pin it over the desktop, or take a follow-up action.
Before you start
- One Shot captures visible windows, regions, or a display. For content that extends beyond the screen, choose an editor post-capture setting and start Scroll Capture from the editor.
- The post-capture result follows your selected setting, so choose an editor option when you want to annotate before exporting.
Frequently Asked Questions
- Can One Shot capture a window, a region, or the full screen?
- Yes. In the same One Shot flow, click a highlighted window, drag a region, or press F to capture the display where the capture session began.
- Do I need to choose a capture mode before starting?
- No. One Shot supports window and region selection in the same interactive flow; F captures the display for that session.
- What happens after I capture something?
- It follows your selected post-capture setting: an editor, the clipboard, or a file.
- Can I make a scrolling screenshot with One Shot?
- Choose an editor post-capture setting, use One Shot to capture the starting area, then start Scroll Capture from the editor for content that continues beyond the visible screen.
- Which shortcuts can I use while One Shot is open?
- The on-screen hint shows the available capture actions. Press F for the display, C to copy the color under the pointer, P to open Live Canvas, or ESC to cancel.
- Can I refine the capture area after I choose a window?
