Rotation is a page attribute, not a redraw
Every PDF page carries a rotation value — 0, 90, 180 or 270 degrees — that tells a reader how to display it. Rotating a page changes that number. The content underneath is not redrawn, re-rendered or re-encoded, so the operation is completely lossless and takes almost no time regardless of page count.
This is why rotating a 300-page scanned document is instant while compressing the same document is slow. One edits a handful of numbers; the other touches every pixel.
Why a page looks sideways in one reader and not another
Because rotation is an instruction rather than a change to the content, it depends on the reader honouring it. Most do. Some older software, some printers and some systems that extract pages ignore the flag and show the page as it was stored.
That is the usual explanation for a document that looks correct on your screen and prints sideways. Rotating in the PDF itself, rather than in your viewer's temporary display setting, is what makes the change travel with the file.
Getting the direction right
Ninety degrees clockwise and ninety anticlockwise are easy to confuse when you are looking at sideways text. The reliable method is to note which edge of the page the top of the text points towards: if the text reads bottom-to-top, it needs clockwise; if it reads top-to-bottom, anticlockwise.
Mixed documents are common with scanners, where landscape tables were fed differently from portrait pages. Rotating page by page rather than applying one rotation to everything is usually what such a document actually needs.
Rotation and printing
Rotating does not change the page's dimensions — a landscape page rotated upright is still a landscape page, and a printer will fit it to paper accordingly. If a document prints with unexpected margins after rotation, the page size rather than the rotation is what needs attention.
For double-sided printing, rotation matters more than it appears: a page rotated 180 degrees will bind along the opposite edge, which is exactly the kind of error that only becomes visible after a hundred sheets have come out.
Safe on any document
Because nothing is re-encoded, rotation carries none of the risks that other PDF operations do. Text stays text, scans keep their resolution, and the file size is essentially unchanged. It is one of the few PDF edits with no downside.
It runs in your browser, so the document is not uploaded. Note that a digital signature will still break, as it does with any modification — rotation changes the file's bytes even though it does not change its appearance.
