Save full web page screenshots in Safari
Use this hidden developer feature to save whole web pages, including parts off the bottom of the screen
Web pages are usually much taller than the screen and when you visit a site in Safari, only the top part of the page is visible. Most of it is hidden off the screen. If you want to save a screenshot of a web page for whatever reason, there is a problem. Screenshots only save what is on the screen and any saved image will not have the parts of the web page off the screen.
