Annotating PDFs in Preview

Annotating PDFs in Preview

You may already know that Preview is a terrific application for viewing PDF files. But did you realize it’s also great for annotating PDFs? It’s a fast and efficient way to share comments when collaborating on group projects.
Under Preview’s Tools menu, you’ll find the options Mark Up and Annotate. Mark Up lets you highlight, strike through, or underline selected text within a PDF. Annotate allows you to draw circles and rectangles around parts of a PDF, append Stickies-style notes, and add hyperlinks.

To use Mark Up, choose the Text tool from Preview’s Toolbar. Select your target text with the cursor, and then choose a Mark Up option from the Tools menu (the choices are Highlight Text, Strike Through Text, and Underline Text).
To add shapes, links or comments, select a command from the Tools menu’s Annotate list (the options are Add Oval, Add Rectangle, Add Note, and Add Link).
If you’ve selected Add Note, simply click anywhere on the PDF. A colored tag appears in the left margin alongside the spot where you clicked. Its default text consists of your user name and the date, though you can alter or add to this by double-clicking on the note. To move notes, double-click their icons (those little cartoon-style balloons) and then drag them. When you double-click a note icon, you can also specify the note’s color and other attributes. To remove a note, double-click its icon and press Delete.
All Mark Up and Annotate tools can be summoned via key command. Also, if you use these tools frequently, you may want to add them to Preview’s Toolbar. (By default, they are not shown.) To add them, select the View menu’s Customize Toolbar command, then drag the tools you want from the pop-up onto the Toolbar.
