Preview: CONVERTING TO TIFF, JPEG, OR PHOTOSHOP

Want to change most any graphic into a Photoshop file? Just open the file in Preview, go under the File menu, and choose Export, where you can export your graphic in Photoshop format. But you're not limited to Photoshop formatPreview will also export your file as a JPEG, PICT, BMP (for sharing files with PC users), PICT, Targa (for video), and more. If the format you're saving in has options (such as quality and compression settings for JPEG and TIFF images), they will appear near the bottom of the dialog.
