Clarify

Sometimes a screenshot requires annotations to explain what you're trying to communicate with the help of that image.

Applications like Clarify were created exactly for this purpose. This Mac utility enables you to take snapshots and add text or geometrical shapes to your screen captures with a minimum of effort.

After you launch the program on your Mac, a new icon is added to your Menu Bar as well as your Dock. You can take snapshots by using a certain key combination (it can be found and changed in the Preferences panel). The app lets you choose the area from your screen that you wish to capture and immediately reveals the snapshot in its main window.

You can add a description to the screenshot, resize the image if necessary, and even attach geometrical shapes to the snapshot. After you finish altering the picture, you can export it as a PDF, DOCX, HTML, PNG or JPEG file and share it with other people.

Furthermore, the program lets you share snapshots via email or Dropbox accounts.

Personally, I really enjoyed using this utility. It was very simple to use, offered me many useful features, and preserved the quality of the screenshots after I exported them. So, it's worth giving it a try if you're looking for an efficient screen capture utility for your Mac.
