Scanners and phone cameras routinely produce PDFs with pages on their side. Rotate every page or just the ones that need it, in quarter turns, and download the corrected file. Rotation is applied relative to how each page currently sits, which is what you want when only some of them are wrong.

Scanners and phone cameras routinely produce PDFs with pages lying on their side or upside down. This tool rotates pages in quarter turns — all of them, or just the ones that need fixing — and lets you download the corrected file.
Rotation is applied relative to how each page currently sits, which is exactly what you want when only some pages are wrong: a page already upright is left alone unless you choose to turn it. That avoids the frustration of a blanket rotation making the correct pages wrong.
It runs in your browser, so the document is not uploaded. Use it to straighten a mixed-orientation scan before sending it, so recipients do not have to tilt their heads or rotate it in a viewer.
