- Upload the PDF you want to inspect.
- Click Detect Rotation — each page's rotation angle (0°, 90°, 180°, or 270°) is shown, with a summary grouped by angle.
Example
A 6-page PDF where three pages were scanned sideways will show "0° (upright)" for the normal pages and "90° clockwise" for the scanned ones — making it easy to decide which pages need rotating before printing or sharing.
Common Use Cases
- Finding which pages in a large PDF have unexpected rotations before printing.
- Checking rotation metadata in a PDF assembled from multiple scanned documents.
- Verifying that a PDF editing tool applied the intended rotation to each page.
FAQ
- What does a 0° rotation mean? The page is displayed upright, in its original orientation as defined in the PDF.
- What is the difference between 90° and 270°? 90° means the page was rotated one quarter-turn clockwise; 270° is equivalent to a 90° counter-clockwise rotation.
- Is my file uploaded anywhere? No — rotation detection happens entirely in your browser; the PDF is never sent to a server.
