If the PDF is sideways, uneven, or mixed in orientation, correct it before OCR, conversion, or external delivery.
Orientation errors become more expensive once the file has already moved through later steps.

After rotation, check the pages that were adjusted rather than assuming the whole document is now correct.
This matters most when scans were merged from different devices or batches.
Perguntas frequentes
Does rotating a PDF reduce quality?
No. Rotation itself should not act like image compression. It changes orientation, not intended reading quality.
Should I rotate before OCR?
Yes, if the pages are clearly wrong. Better orientation usually helps later reading and recognition steps.
