Rotating a PDF file or page

In Skim, you can rotate a PDF file in 90-degree increments. You can rotate and flip an image several times to orient it the way you want it.

To turn all the pages in a PDF file 90 degrees in either direction, choose Tools > Rotate Left or Tools > Rotate Right.

To turn only the currently viewed page 90 degrees in either direction, choose Tools > Rotate Page Left or Tools > Rotate Page Right.

You can also use toolbar buttons to rotate images. To add rotate buttons to the toolbar, choose View > Customize Toolbar and drag the buttons to the toolbar.
