Even if most keyboards already have the "Print Screen" key, it is not very convenient if you want to capture only a selected part of your screen or an open web page. You must then need a tool like CopyIt to make a personalized snapshot.
CopyIt allows you to capture the entire screenshot, either the active screen or a selected area of your screen. To take a snapshot, you can click or use a hotkey that you can change. In addition, you can save the snapshots as BMP, ICO, JPG, WMF, EMF, and PNG, print or send them to a clipboard.
