Annotate lets you draw arrows, boxes and text, blur information, crop and dress up a screenshot before you send it.
Open Annotate
- On the preview card after a capture: click the pencil button Annotate, double-click the card, or hover over the card and press ⌘E.
- Turn on Jump into Annotate in Settings › Screenshot › After Capture to open every new capture straight in Annotate.
- For an image in your clipboard history: right-click › Annotate.
- Choose menu bar › Screenshot › Area & Markup to capture and annotate right where it is (see "Capture and annotate right on screen").
- In Annotate, the … menu › Open Another Annotate Window opens an empty window: drag an image in, or press ⌘V to paste one. If there's an image on your clipboard, OneNotch asks whether to bring it in.

Window layout
- The floating toolbar is at the top; the options for the selected tool sit right below it.
- The column on the right: Resize Image, rotate 90° in either direction, Zoom In, Zoom Out.
- Bottom left: the zoom level; bottom center: a handle for dragging the image into another app.
- The sidebar (hidden by default, press ⌘B): background, padding, shadow, effects.

Zoom with ⌘ + scroll or by pinching; move around with Space + drag or a two-finger scroll. Press ⌘0 to fit the window.
Save and send the image
- Done (⌘S): overwrites the original screenshot file, updates the preview card and closes the window.
- ⌘C (when no shape is selected), ⇧⌘C, Esc or … › Put on clipboard: copies the annotated image and closes the window; your edits are still saved to the original file.
- … › Save as... (⇧⌘S): saves a separate copy as PNG, JPEG or WebP.
- … › Share.
- … › Pin window (⌃⌘P): keeps the window floating above other windows.
- … › Delete: moves the screenshot to the Trash.
- Drag the handle below the image to another app to drop the image there.
For an image from your clipboard history, Done writes the edited image back to that clip.
