Webpage screenshot is very practical. It can be used for demonstration, archiving, or even making e-books. In fact, there are many methods. For example, after installing Acrobat, we can print web pages in PDF format, or use the built-in screenshot program on Apple computers. We could also use the feature-heavy Snapz Pro X, or Paparazzi. However, the use of PDF is limited, the built-in computer function cannot capture webpages beyond the screen display range, Snapz Pro X starts too slowly, and Paparazzi cannot capture pages that only display after logging into the computer. Below, I will introduce a software called Web Snapper, which overcomes the aforementioned problems.
