Frequently asked questions
Can I fix some pages upside-down and others sideways in the same operation?+
Apply one rotation at a time — first correct the 180° pages, then process the 90° pages in a second pass.
Will rotating affect OCR text in the scanned PDF?+
The visual rotation updates immediately. If OCR text was embedded at the wrong angle, you may need to re-run OCR after correcting the rotation.
What if the entire PDF is upside-down?+
Select all pages and rotate 180° in one operation.
