Greenshot is designed to enable you to save a screenshot or a part of the screen to a file within a second, and additionally, you have an option to apply text and shapes to the screenshot.

You can use Greenshot’s image editor not only for screenshots. You can also open images for editing from a file or from a clipboard.

Greenshot is easy to understand and configurable. Therefore it is an efficient tool for project managers, software developers, technical writers, testers, and anyone else creating screenshots.

  • Export the screenshot in various ways. Save to file, send to the printer, copy to clipboard, attach to e-mail, send Office programs. Moreover, you can upload to photo sites like Flickr or Picasa, and others.
  • …and a lot more options simplifying the creation of and work with screenshots every day.

Greenshot is running its own process in the background. To reach the application, you can right-click the Greenshot icon in the notification area or directly take a screenshot by pressing one of the defined keys. Several editor windows can be opened in parallel.

Changes in Greenshot 1.3 Unstable:

New features:

  • The editor now has a zoom, completely built by our awesome community member @KillyMXI PR #201
