Region Capture

What is region capture?

Region capture is the ShareX capture mode for selecting a specific part of the screen. Draw a rectangle around the area you need, or select a detected window or control.

Region capture is useful for screenshots of buttons, dialogs, menus, error messages, form fields, code snippets, sections of web pages, or any other area where a full-screen capture would include unnecessary content. You can draw annotations before selecting the capture area, use the magnifier for accurate positioning, and reuse the last selected region.

Opening region capture

You can start region capture in several ways:

Basic capture workflow

A typical region capture workflow in ShareX is:

  1. Start Capture -> Region.
  2. Choose an annotation tool and mark the screenshot if needed.
  3. Press Tab to activate the rectangle region tool, then drag over the area you want to capture. You can also click a detected window or control.
  4. Release the mouse button to capture the selected region when Quick capture is enabled, as it is by default.
  5. Let ShareX continue with the configured after-capture tasks, such as copying, saving, opening in the image editor, pinning to screen, OCR, or uploading.

Disable Quick capture under Task settings -> Capture -> Region capture if you want to adjust the selection before finishing. Drag inside the selected rectangle to move it, use its resize handles to change its size, then press Enter or double-click inside it to capture.

If you cancel the selection before it is completed, ShareX returns to the previous state without creating a capture.

Region capture tools

Select

Select and move existing annotations, or adjust their available tool options. Press Tab when you are ready to select the rectangle to capture.

Rectangle

Draw a rectangular annotation. Rectangle annotations are useful for highlighting windows, buttons, panels, and other rectangular UI elements.

Ellipse

Draw an ellipse or circle annotation. Use it for rounded highlights or to call attention to a specific area.

Line

Draw a straight line between two points.

Arrow

Draw an arrow to point at a control, message, setting, or area of interest.

Freehand

Draw freehand strokes on the capture. This is useful for quick circles, underlines, handwritten marks, and rough highlights.

Text

Add editable text annotations with text color, outline color, font size, and formatting options.

Speech balloon

Add a speech balloon annotation for short callouts directly on the screenshot.

Step

Place numbered step markers on the capture. This is useful for tutorials, guides, and multi-step screenshots.

Image

Insert an image as an annotation. You can also paste an image from the clipboard.

Emoji

Insert an emoji as a visual marker or callout.

Cursor

Insert a cursor graphic when you need to show pointer position clearly.

Highlight

Highlight an area without fully covering the underlying content.

Smart eraser

Cover small areas by blending with nearby colors.

Blur

Blur a selected area to hide sensitive information such as names, email addresses, tokens, or account details.

Pixelate

Pixelate a selected area to obscure private information while making the redaction obvious.

Magnify

Magnify a small part of the screen so it can be read more easily.

Spotlight

Darken the image outside a selected area to draw attention to one part of the screenshot.

Use the image editor after capture for cropping, cutting out strips, editing the background, or applying image effects.

Capturing monitors and the full screen

With the rectangle region tool active, you can capture the full screen or active monitor without dragging a region:

These shortcuts are useful on multi-monitor setups or when you start region capture but decide that a full monitor capture is faster.
