Why does the rotate button in my PDF reader not stick?

Because it rotates the view rather than the document. Nothing is written to the file, so the next person to open it sees the original orientation. Rotating here writes it in.

Does rotating lose any quality?

None at all. Rotation is a page attribute rather than a transformation of the content, so nothing is re-rendered or re-compressed and the file size is unchanged.

Can I rotate only some pages?

Yes — name the pages that need it. That is the usual case for a bundle containing landscape tables among portrait text.

It still prints sideways.

Some older printers and drivers ignore the page rotation attribute. Printing to a new PDF with the rotation applied flattens it into the content, which every printer respects.

About the Rotate PDF

A PDF page that displays sideways is usually a scan fed in the wrong orientation, or a page inserted from a landscape source. Reading it means tilting your head or rotating the view every time the document is opened, which the next reader will also have to do.

This rotates pages permanently — the rotation is written into the document, so it displays correctly everywhere rather than only in a viewer where you happened to rotate the view.

That distinction is the whole reason to use a tool rather than the rotate button in a reader. Most viewers rotate the display and do not save it, so the document is unchanged and the next person sees it sideways again. Some offer to save, and then only some of them write it in a way every other viewer respects.

Rotation in a PDF is a page attribute rather than a transformation of the content, which has a pleasant consequence: it is completely lossless. Nothing is re-rendered or re-compressed, text stays selectable, and the file size does not change. A page rotated four times is byte-identical to where it started.

You can rotate the whole document or specific pages, which matters for a mixed bundle where the landscape tables need turning and the portrait text does not.

One thing to check afterwards: some older software and some printers ignore the page rotation attribute and print the original orientation regardless. It is rare now, but if a rotated document prints sideways, that is the cause, and the workaround is to re-print to PDF with the rotation applied.

How to use it

1Drop in the PDF.
2Choose the rotation — 90 degrees clockwise or anticlockwise, or 180 for an upside-down scan.
3Apply it to the whole document, or name the pages that need it in a mixed bundle.
4Check the result in a viewer, and print a test page if the document is destined for a print shop.
