📖 How to Use PDF Page Rotator? (Step-by-Step Guide)

Step 1

Upload your PDF containing upside-down or sideways scanned pages.

Step 2

Rotate individual pages using the thumbnail buttons or rotate all pages simultaneously by 90° clockwise, 90° counter-clockwise, or 180°.

Step 3

Verify that every portrait and landscape page reads upright in the visual preview grid.

Step 4

⚙️ Permanent ISO 32000 `/Rotate` Page Dictionary Mutation

Office document feeders and mobile scanners frequently save landscape tables sideways (`90°`) or scan pages upside-down (`180°`). Standard viewer rotation buttons only alter temporary screen state without mutating the file.

DH Tools modifies the official ISO 32000 `/Rotate` integer entry inside each selected page's dictionary in local RAM—permanently locking the correct orientation across all desktop, mobile, and print viewers with zero re-compression.
