You will have access to various modes of capture: window, fullscreen, customized region, last region captured, and capture with scroll (ideal for websites and documents).
Once you've taken the capture, you can edit it using the editing tool that comes with the program. This tool allows you to add text, symbols, arrows, and borders to the capture. You can also resize and crop the image.
As you can see, Screenpresso is a comprehensive and effective tool.
