The tool accepts one PDF up to 50 MB and offers clockwise rotations of 90°, 180°, or 270°. It changes page orientation; it does not deskew a slightly tilted scan, crop dark edges, run OCR, or reflow landscape content into a portrait layout.
All pages works for any page count. To protect performance, selected pages shows thumbnails for only the first 30 pages, so pages after 30 cannot be individually selected in the current interface. For a longer document, split out the target range, rotate it, and merge it back.
Example: correct two sideways scans
In an eight-page scan, only pages 2 and 5 lie sideways to the left. Choose clockwise 90°, selected pages, and click thumbnails 2 and 5. The action should say two selected pages; pages 1, 3, 4, and 6–8 should retain their original orientation.
Common failure cases
The operation cannot start when selected-page mode has no selection. Password protection, damage, or a disguised file format prevents reading, and high-resolution scans can exhaust memory on a phone. The source remains unchanged; close other tabs or process a smaller split file in a desktop browser.
