The Acrobat Rotate PDF pages tool lets you flip a PDF by rotating one or more PDF pages to the left or right. Upload a file or multiple files, then select the pages you want to rotate. The Acrobat online tool also lets you reorder pages by dragging and dropping page thumbnails or delete selected pages by using the trashcan icon. You can insert up to 100 files too, each with a maximum of 500 pages. The total number of pages in your rotated PDF can be up to 1,500 pages, with a maximum file size of 100MB.
