Convert Images into a PDF
Converting an image into a PDF file is as simple as opening it in Preview and
clicking Print from the File menu. Then, in the dialog box that appears, click
the PDF drop-down at the bottom left and select Save As PDF.
To do the same for a whole series of images, open them in Preview by multiple-
selecting them in Finder (that is, holding down
COMMAND
or
SHIFT
and selecting
more than one file) and then dragging them onto the Preview Dock icon. This
will open the images in a drawer to the left of the window. Select all of them
(click one of the thumbnail previews, and then hit
COMMAND
+
A
), and click File
→Print. In the dialog box, click the PDF button before clicking the Save As
PDF option.
To avoid pictures being rotated, uncheck the Auto Rotate box in the Print
dialog box.

list, and then in the list of applications double-click Terminal within the
UTILITIES
folder), and type the following:
DEFAULTS WRITE COM.APPLE.DOCK SINGLE-APP -BOOL TRUE;KILLALL DOCK
The changes will take effect the next time you click the Dock icon. Click any
Dock icon to hide all other program windows.
