How to turn a PDF document upside down

How to save rotated Adobe pdf file?

I'd like to rotate by 180 degrees each page in a high-resolution .pdf, but don't know how. In ImageMagick, using 'convert -flip -flop' lowers the resolution significantly, while increasing the file size slightly. This also happens (to a lesser extent) in LibreOffice, an example of open-source PDF editors. Any ideas, besides buying Adobe Acrobat? (which may or may not solve the problem!)

Thanks, I read the solution there which suggests PDFcreator. Printing from Adobe Reader in Windows XP, I don't see a 'rotate' option in PDFcreator. Any other ideas? – Mark – 2011-04-18T14:23:06.993

PDF Split and Merge (pdfsam) has a processing option to rotate PDFs.

1Thank you, that did it. (My version of PDFsam was over a year old and didn't have this feature. Version 2.2 works great: same resolution, and same file size.) Much appreciated. – Mark – 2011-04-18T14:38:04.797

The free PDFill PDF Tools can rotate the pdf, entirely or selectively, as well as doing many other useful operations on PDFs.
