Greenshot

Greenshot is a lightweight screenshot tool for Windows. It quickly captures a selected region, a window or the full screen.

Its editor annotates, highlights or obfuscates parts of a screenshot, for example to point out a defect or hide sensitive data before sharing it. Screenshots can be saved to a file, printed, copied to the clipboard, attached to an e-mail, sent to Office programs or uploaded to other destinations through plugins, which helps testers document issues found during testing.

Greenshot is free and open source under the GPL-3.0 licence.
