People often take screenshots of web pages for miscellaneous reasons - when designing a page, debugging a web application, or even for graphical reference. Usually, though, only a portion of the screenshot is actually relevant to the user's purpose, leading to a large portion of the image getting cropped. This can be time consuming, and annoying at times.
Snapper allows users to designate an area of a web page for a focused snapshot, cutting out the additional work needed for cropping unecessary information. And starting with version 2.1, Snapper can also be used to capture a screenshot of an entire webpage, the visible portion of a webpage, or even a specific frame on a webpage.
