How do I take a screenshot of an entire page of a website?

interesting question 

To take a screenshot of a full page of a website, you can use the built-in tools of a browser such as Google Chrome or Microsoft Edge: open the developer tools magento agency, call the command "Capture full size screenshot". To simplify the process, you can use extensions such as Awesome Screenshot or GoFullPage. If you need a professional solution for managing web pages, contact MageCloud Agency, which specializes in developing and scaling online stores and websites. 

I usually create screenshots of websites in Senlix, it's a convenient solution thanks to which you can take screenshots very quickly, without downloading any programs or wasting time installing extensions. You only need to enter the url of the site and the Google API key, and how to get it is written in detail in the description of this solution, here try it yourself https://senlix.com/tools/screenshot.
