It's easy to rotate an individual page in a PDF using Acrobat online services. Upload a file and sign in. Then select the single page you want to rotate and click the rotate clockwise or rotate counterclockwise icon. You can select single pages, a range of pages, or multiple pages that are not ordered consecutively to rotate them at the same time if desired. If you want to reorder pages, simply drag and drop them. You can also delete any selected page by clicking the trashcan 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 content, convert PDFs, add page numbers, insert bookmarks, add watermarks, split a PDF by page range, and more.
