Screenshot tools are software applications that allow users to capture images of their computer or mobile device screens. These tools can capture the entire screen, a specific window, or a selected area, making it easy to save and share visual information. Many screenshot tools also offer editing features, such as adding annotations, arrows, or text to the captured images. Popular screenshot tools include built-in options like the Snipping Tool on Windows and Screenshot on Mac, as well as third-party applications like Greenshot and Snagit. These tools are useful for creating tutorials, sharing information, or documenting issues for technical support.
