Acrobat online services make it quick and easy to set up a PDF just how you need. Simply drag and drop PDF pages to reorder them. You can also rotate a selected page to landscape or portrait mode by clicking the rotate clockwise or rotate anticlockwise icon. To delete a page, select it and click the dustbin icon.
For more advanced PDF tools, you can try Adobe Acrobat Pro DC for free for seven days on Windows or Mac. The free trial lets you edit PDF text and images, add page numbers, extract pages, convert PDFs, insert watermarks, split PDFs, reduce file size and more.
