How do I permanently rotate a PDF and save it?

Use a tool that modifies the PDF file directly — not just the viewer. Free online tools like PDF24 or Smallpdf rotate and save in one click. On Mac, open in Preview, use the Rotate command, then save with ⌘+S.

Why does my scanned PDF come out sideways?

Sideways scans happen when paper is loaded into a scanner in landscape orientation, when auto-rotation software misreads the page, or when a phone camera captures a document while held horizontally. Mixed portrait and landscape batches are especially prone to this issue.

Can I rotate just one page in a PDF?

Yes. Most PDF tools let you select individual pages before rotating. Online tools like Smallpdf and PDF24 show page thumbnails so you can choose only the pages that need fixing — leaving the rest untouched.

Does rotating a PDF in Chrome or Edge save the rotation?

No. Chrome and Edge's rotate buttons only change the on-screen display — the underlying file stays unchanged. When you reopen the document, it reverts to sideways. You need a tool that modifies and resaves the actual file.

How do I rotate a PDF on iPhone?

Use a free online tool like PDF24 in Safari — upload, rotate, and download in under a minute. The Scanjet app also lets you scan documents in the correct orientation from the start, preventing the problem entirely.
