Rotate PDF Pages Online — Fix Duplex Scans & Saddle-Stitch Prep
Rotate all pages in a PDF, or rotate odd and even pages in different directions. Built for scanning operators fixing duplex documents where alternating pages fed upside-down, and prepress technicians preparing booklets for saddle-stitch imposition.
Rotation Options
Choose a mode, then a rotation angle. Alternating mode lets you rotate odd and even pages in opposite directions — the standard fix for duplex scans fed upside-down.
Tip: For duplex scans fed upside-down, leave odd at 90° CW and set even to 90° CCW (or vice versa).

How do I rotate every other page in a PDF to fix duplex scans?
Upload the PDF, choose Alternating mode, set Odd Pages to 90° CW and Even Pages to 90° CCW (or vice versa depending on which side was fed upside-down). Every even page is rotated opposite to every odd page, fixing a duplex document scanned on a single-sided ADF.
What is the best tool to rotate alternating PDF pages for booklet printing?
Use a PDF rotator that supports per-parity rotation. Printssistant's PDF Rotator lets you set separate rotations for odd and even pages in one pass, which is the standard operation for rotating booklet interiors before saddle-stitch imposition.
Can I rotate odd pages clockwise and even pages counterclockwise in one PDF?
Yes. Select Alternating mode, set Odd Pages Rotation to 90° Clockwise and Even Pages Rotation to 90° Counterclockwise. The tool processes the whole PDF in one pass — no need to split odd and even pages into separate files.
Does this rotate PDFs that already have a rotation applied?
Yes — rotations are additive. If a page is already rotated 90° and you apply another 90° CW, the final rotation will be 180°. Upload and process as normal; the tool respects existing page rotation flags.
