Input: "scanned-document.pdf" (20 pages, 6.2 MB)
Situation: A multi-page scanned PDF where pages 3, 7, and 15 were scanned upside-down (180°), and all pages were captured in landscape orientation but should be portrait (90° CW).
Step 1 - Upload: Drop scanned-document.pdf onto the upload area. After loading, all 20 pages appear as thumbnails. Pages 3, 7, and 15 are visibly upside-down.
Step 2 - Fix orientation: Click Rotate All CW to rotate every page 90° clockwise (fixes landscape→portrait). Then click the 180° button on pages 3, 7, and 15 to rotate them an additional 180° (correcting the upside-down issue). The summary updates to show "20 pages total · Rotating 20 pages."
Step 3 - Process: Click the floating Rotate 20 Pages button. The spinner appears and completes in approximately 5 seconds.
Output: "scanned-document-rotated.pdf" — all pages in portrait orientation with pages 3, 7, and 15 correctly oriented. Ready for sharing or printing.
