Most people know how to take screenshots of a particular area on the scree, but how to capture the entire page?
Full-page screenshots are handy when the content or design that needs to be captured doesn’t fit on one screen. Capturing a whole page lets you view and save the entire layout if you want, for instance, to save the menu of a restaurant, a web page design for future reference or troubleshooting, etc.
See the guide to quickly taking full-page screenshots in different browsers.
