If you’re a regular user and you don’t want to play with any of the settings, then go with the default Greenshot installation. But if you’re an advanced user, then you’ll be glad to know that you can customize the installation process.
The easiest way of taking a screenshot is by using a hotkey: Print to screenshot a region, Alt + Print to screenshot a window, Ctrl + Print to screenshot the entire screen.
Greenshot features a basic image editor which you can use to edit screenshots. You can use this editor to crop a screenshot, to draw shapes on the screenshot, to apply a filter, and so on.
Once you’re done taking and editing your screenshot, you can save it anywhere you want on your PC. You can save it as a JPG file, as a PNG file, as BMP file, and more.
Boot up your computer and Greenshot will be waiting for you to start using it. That’s because it can automatically launch at startup.
