Not just a temporary viewer turn.
Some PDF readers can rotate only the current view. Doruni writes each chosen 90-degree change into the output document so the orientation follows the file.
- Rotate left or right in 90-degree steps.
- Mix different orientations in the same document.
- Existing page content is not re-rendered as an image.
A precise structural change.
Doruni changes each selected page's rotation value. The page content keeps its original quality.
Best forSideways scans, upside-down pages and mixed portrait/landscape documents.
Angles90°, 180° or 270° through repeat left/right turns.
ScopeIndividual pages or every page at once.
Important limitRotation changes orientation, not skew or perspective inside a scanned image.
What happens when pages turn.
Can I rotate only one page?
Yes. Each thumbnail has its own left and right rotation controls.
Can I rotate every page together?
Yes. Use the rotate-all controls and then adjust individual exceptions if needed.
Does rotation reduce quality?
No raster conversion is used. Doruni changes the PDF page rotation value rather than recompressing page artwork.
Can this straighten a slightly crooked scan?
No. This tool works in 90-degree steps; deskewing a scan by a small angle is a different image-processing task.
