Scanned a document and every page came out sideways? pdf2pageturn.com turns your PDF the right way up. The rotate tool spins every page 90° clockwise and saves a corrected file — run it again to reach 180° or 270°. The rotation is baked into the PDF itself, so the pages stay upright in every viewer, not just yours.
It's free, runs online, and adds no watermark. The document's text and structure are preserved — only the page orientation changes.
Why scanned PDFs come out sideways
Scanners and phone scanning apps record pages in whatever orientation the paper was fed, then store that orientation in the file. Some viewers auto-correct on screen but the underlying pages stay rotated — so the moment you print or open the file elsewhere, it's sideways again. Rotating the pages and saving bakes the correct orientation into the document, fixing it everywhere for good.
Rotate, split, merge
Turning pages is often step one of tidying a document. Once orientation is fixed you can split the PDF into single pages, merge several files into one, or export pages as images with PDF to JPG.
