Helper app to share only a part of a screen via video conference apps

Region to Share

A Windows helper app to share only a part of a screen via video conference apps that only support either full screen or single window like e.g. Teams, WebEx, etc.

How it works

This tool simply mirrors the content of a screen region into a hidden window. In your meeting app you then can just share the content of this hidden window.

Region to Share is not aware of your meeting app nor what the meeting app is doing with the content of the window. It's up to your meeting app whether it properly shares this hidden windows content or not - if it's not working as expected, there is nothing Region to Share can do about this.

Prerequisites

  • Windows 10 or 11
  • DotNet 4.6.2 or newer

Installation

  • Download and install this app from the Windows Store or pick the latest binaries from the release page

Usage

Tutorial

Quick Start

  • Start the "RegionToShare" app.

  • Move the window to the region you want to share.

  • In your meeting app start sharing the window "Region to Share".

  • Now click the "Region to Share" window to start sharing the selected region. The window will change to the region selection frame, and others are seeing what's inside this frame.

  • Close the region frame to stop showing the region without stopping to share.
