PDFelement for Mac enables you to rotate pages in a PDF document.
Open one file and click the "Organize Pages" icon on the top left.
Click "Rotate " in the pop-up window. Click a single page or hold the Command key and click multiple pages to be selected, or select the pages you want to rotate in the right panel, and then choose the rotate direction on the bottom.
Alternatively, you can go to the Thumbnail Panel, right-click a page you want to rotate, and select the "Rotate" option in the drop-down menu.
