Save Images as GIF & Other Image Formats in Preview for Mac OS X
Preview is a great basic image editing app bundled with Mac OS X, but newer versions of Mac OS have simplified the available image Export Format options down to JPEG, JPEG 2000, OpenEXR, PDF, PNG, and TIFF. Or at least that’s what you see on first glance, but it turns out you can still access all the traditional image format options from the Save, Save As, and Export screens just by using a simple key modifier when saving a file in Preview app on the Mac.
This is kind of a little known secret (well, at least until we told you about it!) but once you learn how to use it, you’ll be able to reveal many image format save options in the Preview for Mac application.


Dashboard got a user interface overhaul with new versions of OS X and it now more closely resembles – surprise surprise – iOS and OS X’s very own Launchpad. You’ll find the new look when you go to add a widget to the Dashboard, and just like iOS you can now arrange all those widgets into Folders to prevent clutter and bring some organization to the widget collection.
