Rotate all pages or only selected pages
Use All pages when the whole document has the wrong orientation, Odd or Even for alternating scan problems, or Custom pages for syntax such as 2, 5-8.
Toolmera validates custom page numbers against the actual PDF page count before saving.
How permanent PDF rotation works
Toolmera reads each selected page’s current rotation angle and adds 90 degrees clockwise, 90 degrees counter-clockwise or 180 degrees.
The page content is not rasterized into screenshots during this operation; the updated document is saved as a new PDF.
