How to: step-by-step
- Select the scanned PDF.
- Choose automatic detection or enter a manual correction angle.
- Select the pages to process and run Deskew PDF.
- Download and compare line alignment, borders and page edges with the original.
Tips for better results
- Use manual correction when automatic detection struggles with diagrams or sparse text.
- Apply OCR after deskewing, not before.
Common pitfalls
- A sideways page needs Rotate PDF first.
- Automatic detection can be inaccurate on decorative or mostly blank pages.
Before you finish
Processed pages become images and page dimensions may change to fit the rotation. Existing text layers on those pages are not retained.
