This calculator needs JavaScript to run. You can work it out by hand: Rotated document = input PDF with specified pages rotated by +90° (clockwise) or -90° (counter-clockwise). Multiple angles supported in 90° increments.

Rotated PDF saves the document with selected pages rotated. Clockwise rotation is positive angle; counter-clockwise is negative.

How PDF Page Rotation Works

PDF page rotation is performed client-side using PDF.js:

1. The PDF is loaded and thumbnails are rendered 2. User clicks rotation buttons on thumbnails (each click rotates 9° in the selected direction) 3. The PDF canvas is transformed for selected pages only 4. A new PDF Blob is generated with the rotated pages 5. The rotated PDF is available for download

**Rotation angles**: Each button press rotates the page by 90° increments: - ↺ (clockwise): +90°, +180°, +270°, back to 0° - ↻ (counter-clockwise): -90°, -180°, -270°, back to 0°

**Preview**: Thumbnails update instantly after each rotation, so you can see the result before downloading.

Worked Example

Example: Rotating specific pages in a 10-page report:

Problem: The first page (cover) is upside-down, and pages 3-5 are sideways.

Using the rotator: - Click ↺ on thumbnail 1 (cover) → rotates to upright position - Click ↻ on thumbnails 3, 4, 5 → each click rotates -90°, bringing them to upright - Result: All 10 pages downloaded with cover + pages 3-5 now upright, other pages unchanged

The thumbnail grid shows a small compass rose (🠗/𠠞) on rotated pages to indicate the angle.
