Rotate PDF

Rotate pages in a PDF by 90 degrees clockwise or counterclockwise. The tool shows thumbnail previews of every page, letting you rotate them individually or apply a bulk rotation to the entire document.

How It Works

  1. Upload a PDF file. Thumbnails for every page render in a grid.
  2. Use the left/right rotation buttons below each page thumbnail to rotate that specific page.
  3. Use the bulk rotation controls at the top to rotate all pages at once.
  4. The thumbnail preview updates in real time to show the rotation.
  5. Click the process button to save the rotated PDF.

Features

  • Per-page rotation in 90-degree increments (left or right)
  • Bulk rotation for all pages simultaneously
  • Real-time thumbnail preview with animated rotation transitions
  • Lazy-loaded thumbnails for smooth performance on large documents
  • Preserves original page content and quality

Use Cases

  • Fixing sideways or upside-down scanned pages
  • Rotating landscape pages to portrait orientation (or vice versa)
  • Correcting a mixed-orientation document where some pages were scanned at the wrong angle
  • Preparing a document for a specific display orientation

Tips

  • Rotations are cumulative. Clicking the clockwise button twice applies a 180-degree rotation.
  • For non-90-degree rotations (e.g., 45 degrees to fix a slightly tilted scan), use Rotate by Custom Degrees instead.
  • The bulk rotation controls affect all pages, not just selected ones. There is no selection mechanism in this tool -- for that, use PDF Multi Tool.
