Snipping Tool Alternatives
The ability to capture a screenshot of a specific region of your screen and then have quick access to basic editing and annotating is what Microsoft's Snipping Tool for Windows is all about.
Snipping Tool can be used to capture a screen shot of any object on your screen which can then be saved, annotated, and shared as an image.
As a relatively basic option, there are alternatives that focus on providing features such as the ability to upload directly to image hosting sites such as Imgur directly within the app. Other alternatives can provide more advanced features that Snipping Tool doesn't have, such as scrolling captures.
