Rotate PDF is a software tool or application designed to rotate pages within a PDF (Portable Document Format) file to the desired orientation. Whether correcting upside-down pages or adjusting sideways documents, this tool allows users to rotate individual pages or entire PDF files with ease. It supports both single-page and multi-page PDFs and offers customizable rotation options such as 90°, 180°, or 270° angles. By providing a quick and efficient way to fix orientation issues, the Rotate PDF tool ensures improved readability, presentation, and usability of PDF documents.
