Single-page rotation is for mixed-orientation documents
If most of the PDF is upright but one inserted scan, one receipt, or one appendix page is sideways, rotate only that page with 旋转 PDF.

How to rotate one page in a PDF
Sometimes only one page in a document is sideways. In that case the right workflow is not rotating everything. It is fixing only the page that was scanned or inserted with the wrong orientation.
This is different from rotating the whole file
Rotating all pages makes sense only when the entire document is wrong by the same angle. If only one page is wrong, rotating everything creates a new problem on the other pages.
Typical cases
Common examples include one landscape scan inside a portrait packet, one phone-captured page that came in sideways, or one receipt page inserted at the wrong angle.
Rotation only changes orientation
It does not OCR text, remove blank pages, or extract the corrected page as a separate file. Those are separate workflows.
What to do next after rotation
If you want that corrected page as its own file, continue with 拆分 PDF. If the document also contains blanks or duplicates, clean it with 删除 PDF 页面.
