About:

Preview is a software tool built right in to your Mac that allows you to view images and PDFs.  But that's not its biggest benefit!  The program also allows you to edit images and PDFs.

Caveat!  There is no 'undo' once you've saved.

 
Preview is not an image management application like iPhoto. The adjustments you make to images in Preview can be destructive. (In iPhoto, all your original images are retained no matter how many adjustments you make to images inside the application.)  However, with Preview, you will need to make a duplicate copy of the original image before you edit photos, or do a 'Save As' in order to retain the original after the adjustments are made.
