How to rotate a PDF 90 degrees
Sometimes PDF pages appear sideways or upside down after scanning or exporting a document. This can happen when scanners or mobile devices capture the page but store the orientation information incorrectly. As a result, the document may open with pages rotated in the wrong direction, making the content difficult to read. Rotating a PDF by 90 degrees is a simple way to fix this issue and restore the correct page orientation. Once the pages are rotated, the document becomes easier to read, share, and print. Online PDF tools allow you to rotate one page, several pages, or the entire document quickly without installing any software.
Why PDF pages may be rotated incorrectly
Incorrect page orientation often occurs when documents are scanned or converted from image files. Some scanners detect the page layout automatically but may save the rotation metadata incorrectly. Similarly, photos taken with smartphones may store orientation information that is interpreted differently by PDF viewers. This can cause pages to appear sideways when opened on different devices or software.
When you should rotate PDF pages
Rotating a PDF is useful whenever pages appear sideways, upside down, or incorrectly aligned. Correct orientation is important when sharing documents with colleagues, submitting files online, or preparing documents for printing. Ensuring the pages are properly aligned improves readability and prevents confusion when viewing the document.
How to rotate PDF pages by 90 degrees
