‘Screen Capture’ (by Google) is an effective and useful extension for Google Chrome, which allows users to quickly and easily capture quality screenshots of WebPages. The extension has 3 screen capture modes: capture visible content of a tab, a region of a web page, or the whole scrolling webpage as a PNG image.
It also offers some editing tools to edit the screenshot before saving it. The screen captures can also be copied to clipboard in a simple click.
You can choose ‘Autosave’ from Options if you prefer to take screenshots quickly without doing any editing. This way captures will be automatically stored in the default save location, followed by a message in the bottom right corner to access them.
This extension does a great job. Do give it a try!
