Turn one page or all of them
Each press turns a page 90° clockwise, so press up to three times to reach any direction. Rotate all turns every page at once, which fixes a whole scan fed in sideways.
Rotation is stored in the file
The page keeps its content and gains a rotation setting, the same way PDF viewers rotate pages. Nothing is re-rendered, so text stays sharp and searchable.
Questions
Does rotating reduce quality?
No. The page content is copied as is and only its rotation value changes, so text and images keep their quality.
Can I rotate just one page?
Yes. Use the turn button under that page. Other pages stay as they are.
Does it change my original file?
No. You download a new PDF and the original stays untouched.
Are my PDFs uploaded anywhere?
No. Pages are read, rearranged and saved by your browser. The site is not allowed to send data to any other server, and it keeps working offline after the first visit.
