I've taken a screenshot, how do I edit it? [duplicate]

Solution 1:

There is a default application named Preview in OS-X for editing images.

If you created any screen shots, just open that screenshot image in Preview application and you can see the edit toolbar to edit the image.

Solution 2:

Depending on your needs you could use one of these free tools:

• Apple's Preview (Built-in with OSX)
• Gimp
• Sketchbook Express

If you want something more advanced you could try

• Adobe's Photoshop
• Pixelmator

Solution 3:

I found another application named Skitch for Mac to edit the screenshot. There are many features like free hand circles (which is not available in the Preview app) are available in this application.
