I am looking for a Google Chrome extension that can take full-page, high-definition screenshot of a webpage.
I tried Full Page Screen Capture but screenshot of a webpage aren't high-definition:
Same issue with Nimbus:
Instead of using a plugin you can use a headless instance of chrome using your current user profile and let it render the page into a Chrome window of your size and then save it as PNG image using the following command-line
C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --headless --disable-gpu --window-size=2000,5000 --user-data-dir="%LOCALAPPDATA%\Google\Chrome\User Data" --virtual-time-budget=10000 --screenshot=chrome_screenshot.png https://stackoverflow.com/questions
When I execute this command the generated PNG image has a pretty good quality to me. And by the custom window size (which can be larger than your physical screen resolution) nothing has to be scrolled to make the screen-shot.
