What to expect
A new file is created. Your original files are never modified.
- Works best on text pages tilted by up to about 6°. Pages with little text are marked uncertain and skipped by default.
- Straightened pages are re-rendered as images, so their text is no longer selectable. Run OCR afterwards if you need searchable text.
- Rotation moves the corners: parts rotated outside the page are cropped and new corners are white.
