ShareX

Region Capture

What Is Region Capture?

Region capture is a ShareX feature that lets you select a particular portion of your screen. Instead of capturing the entire display or just the active window, you can outline the precise area you need using a rectangle, ellipse, or a freehand shape.

This feature is ideal for screenshots of interface elements like buttons, menus, dialog boxes, error messages, form fields, code sections, or parts of web pages—any instance where a full-screen image would contain superfluous information. During the capture process, you can also add annotations, copy size and position details, reuse the previous selection, or capture multiple areas, depending on your task settings.

How to Start Region Capture

You can initiate region capture through several methods:

Typical Capture Process

Here's a common sequence for performing a region capture in ShareX:

  1. Start Capture -> Region.
  2. First, add any region capture annotations if you wish to mark the screenshot prior to capturing.
  3. Click and drag your mouse over the desired area.
  4. Release the mouse button or press Insertto complete the selection. ShareX will then instantly capture the chosen region.
  5. Allow ShareX to proceed with configured post-capture actions, such as copying, saving, opening in the image editor, pinning to the screen, performing OCR, or uploading.

If Multi-Region Captureis enabled, selecting an area does not instantly finalize the capture. You can create, move, resize, and adjust multiple regions. Then, pressEnter or double-click to capture them.

If you cancel the selection before completing it, ShareX will revert to its previous state without creating a capture.

Region Types

Rectangle

The rectangle is the most common region shape. Use it for capturing user interface elements, windows, specific webpage sections, dialog boxes, and most standard screenshot selections.

Ellipse

Ellipse captures an oval or circular area. This is useful for drawing attention to a rounded subject or for creating screenshots with non-rectangular shapes.

Freehand

Freehand allows you to define a custom-shaped region. Employ this option when the screen area you wish to capture does not fit a rectangular or elliptical form.

Region Capture Tools

Rectangle

Draw a rectangular annotation or selection. Rectangle annotations are helpful for highlighting windows, buttons, panels, and other rectangular UI components.

Ellipse

Draw an ellipse or circle annotation. Use this for circular highlights or to emphasize a particular area.

Freehand

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

Freehand Arrow

Draw an arrow freehand to point at a specific item, maintaining a hand-drawn look.

Line

Draw a straight line between two points.

Arrow

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

Text

Add text annotations. Region capture supports text styles like outline text and background text.

Speech Bubble

Add a speech bubble annotation for brief callouts directly on the screenshot.

Step

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

Magnify

Magnify a small portion of the screen to enhance readability.

Image

Insert an image from a file or directly from the screen as part of your capture annotation process.

Sticker

Add a sticker annotation to serve as a visual marker.

Cursor

Add a cursor image to clearly indicate the pointer's location.

Smart Eraser

Blend small sections with surrounding colors to seamlessly cover them.

Blur

Obscure names, email addresses, tokens, or account details by blurring a chosen area.

Pixelate

Pixelate a selected section to make private data unreadable and visibly redacted.

Highlight

Emphasize an area without completely obscuring the content beneath it.

Crop image

Trim the captured image to only include the selected area.

Cut out

Remove a segment of the capture, typically to shorten the image or eliminate unused space.

Capturing Full Screens and Monitors

When the region capture tool is active, you can quickly capture a monitor or the entire screen without having to manually draw a selection box:

These shortcuts prove beneficial in multi-monitor setups or when you begin a region capture but then decide a full monitor capture is more efficient.
