How to rotate a PDF
Use ↺ / ↻ on a page to turn it 90°, or the “Rotate all” buttons for the whole document. Drag thumbnails (or use ← →) to reorder, and ✕ to remove a page. Press “Save PDF” when the preview looks right.
Permanent, lossless rotation
The rotation is written into the PDF itself, so it stays fixed in every viewer, on every device. Page content is not re-rendered, so text and images keep their original quality.
