Winning with Chrome DevTools: How to Capture Full Page Screenshots
A lot of people are yet to discover the amazing things they can achieve with Google Chrome. Those without the desire to explore do not really know the usefulness of a tool within their reach. To some, Chrome is just a browser, to others, it is a great tool.
Chrome DevTools is a set of web developer tools built directly into the Google Chrome browser.
With Chrome Developer Tools (DevTools), you can access hidden and experimental settings one of which is discussed in this article.
Screenshots are very essential for visualization in education, during presentations, technical support etc. There are scenarios where capturing a full page screenshot of a web page is needed and not just the viewport (the visible area of the web page) but achieving this earlier has not been easy. With the introduction of full page screenshot functionality in Chrome DevTools, the stress we usually go through using photo editors to combine different sections of a captured web page has been eliminated.
Sometime last year, I was in need of capturing a full page screenshot of an online course I took. I spent a good amount of time capturing chunks of it and then combining them using Adobe Photoshop to create the view I wanted. Not long after, Chrome released a new version with the ability to capture full page screenshots. I was happy when I watched the video from the “What’s New” section of Chrome DevTools. At last, I wouldn’t have to spend time combining chunk of captured viewports.
To access the DevTools of any web page,
Launch the Google Chrome browser and open DevTools using any of the methods below:
- Using Quick Link: Right-click on any part of the browser and select Inspect option
- Using Chrome Menu: Click Customize and control Google Chrome (the three vertical dots at the top-right corner) > More tools > Developer tools.
